Undercut in Welding and How to Avoid Them

what is undercut in welding

Welding is not just about melting two metals and joining them. The job is neither easy nor insignificant. You need to have steady hands and the ability to handle an intricate process. Sometimes even seasoned welders can let the ball drop and make tiny mistakes, causing a bigger negative impact. Welding requires a delicate balance of heat, pressure, thickness of metal, shielding, fusion, and so on. At times, either due to technical issues or due to human error, imperfections can take place. Major ones are undercut in welding and porosity, in addition to cracks. Let’s have a bird’s-eye view of causes of undercut in welding:

what are undercuts in welding?

Undercut: What is Undercut in Welding?

An undercut is a groove that forms at the toe of the weld, where the base metal meets the weld bead. It’s essentially a small channel eaten out of the base material due to either excessive heat or improper welding technique. This weakens the joints, increasing the chances of a failure point because stress gets concentrated at the groove.

Porosity

Tiny holes or air pockets can get created and trapped inside the weld metal because of contamination or gas entrapment during the cooling period. It’s like having air bubbles inside concrete. It reduces density and weakens the weld. Too many such occurrences can harm the overall strength of the component or the buildup. Porosity is likely to happen in aluminum.

Incomplete Penetration

Happens when the weld bead does not extend through the full thickness of the joint. This often occurs when the heat is insufficient or the preparation is inadequate, leaving an unbonded section between pieces. This can heavily weaken the structures.

Lack of Fusion

When the weld metal fails to fuse completely with the base metal or with the previous weld bead. It’s often caused by low heat input, improper electrode angle, or contamination like rust or paint.

Cracks

Cracks can occur hot (while the weld is cooling) or cold (after the weld has fully cooled). Hot cracks often result from high shrinkage stress; cold cracks are often related to hydrogen embrittlement. Even the tiniest crack can propagate under load, so they’re one of the most serious defects.

Overlap

This is when weld metal flows beyond the toe of the weld but doesn’t fuse with the base metal. Basically, the metal just sits on top like melted candle wax without forming the welded joint.

Spatter

Small molten droplets that stick to the surrounding surface, often caused by too high voltage, incorrect polarity, or unstable arc. They’re more of a cosmetic issue but still require post-weld cleanup.

Distortion

Warping of the base metal due to uneven heating and cooling. It can throw off tolerances and require corrective work.

How do Undercuts Occur?

As mentioned, undercuts are grooves that form along the toe of the weld. They usually causes of undercut in welding because:

  • Travel speed is too fast — not enough filler metal to fill the edge.
  • Excessive heat input — melts the edge of the base metal away.
  • Incorrect electrode angle — directing heat in the wrong spot.
  • Undercuts aren’t just “ugly welds” — they create stress concentration points, which can become the starting point for cracks under load.

A “groove” can mean an unwanted depression in the metal surface caused by too much heat or erratic torch movement. It’s like a concave surface due to poor technique.

Deppresion

These are shallow, sunken areas in the weld bead where filler metal is lacking or cooling was too fast. A depression in the weld cap can indicate improper filler deposition, arc instability, or poor weaving technique. Like undercuts, depressions can reduce the cross-sectional strength of the weld.

How to Prevent Undercut when Welding

If you want to avoid undercuts, you need to master heat control, travel speed, and filler metal deposition. Here’s the full playbook and best practices to avoid welding undercuts:

1. Adjust Travel Speed

Maintain a steady and not a hurried pace while taking care of a weld. This will let you focus properly. Going too rapidly will hinder the balance between the molten pool and filler. This situation won’t let you fill the edges, creating a groove. A slow and steady pace will enable full coverage without overheating the base metal.

2. Control Heat Input

While applying heat, one needs to keep in mind that Excessive amperage burns away the edges. It is recommended to follow the recommended amperage settings for your electrode size and metal thickness.

3. Mind Your Electrode Angle

Angles that are too steep radiate heat at the edge rather than the center of the bead. To avoid wastage of heat and material, maintain the correct angle (usually 5°–15° from vertical).

4. Multiple Passes for Thick Material

For thicker metal pieces, make multiple smaller passes instead of one high-heat pass. This will take care of the details while carrying out efficient welding.

5. Use the Right Filler Metal

Match filler composition and diameter to the workpiece and process to ensure proper bead buildup.

5. Clean the Joint Area

Contaminants can cause inconsistent arc behavior, leading to edge erosion. Always grind, wire-brush, or clean with solvent before welding.

These specific techniques will help your welds remain strong and error-free. At the end, the overall design with benefit from robust welding works. Undercuts are not inevitable; they are avoidable for the sake of the strength of the built-up. At Mobile Welding Service, our expert welders can provide you with accurate welds.

How to Weld Aluminum

guide on how to weld aluminum

Aluminum is one of the most widely used metals in Ontario industries,  from automotive and aerospace to construction and custom fabrications. While it’s lightweight and durable, welding aluminum isn’t as straightforward as welding steel. Its softness, high thermal conductivity, and oxide layer make it tricky for beginners.

Whether you’re curious about the process or considering a project, this guide explains how to weld aluminum, how to weld aluminum to aluminum, and when it’s best to hire a professional aluminum welding service near you.

Why Welding Aluminum is Different

Unlike steel, aluminum reacts quickly to heat. It can warp, crack, or form porous welds if not handled properly. Here are the main challenges:

  • Oxide layer: Aluminum naturally forms a thin oxide coating that melts at a higher temperature than the base metal. This makes cleaning essential before welding.
  • Heat conductivity Aluminum dissipates heat fast, meaning more power is often required to maintain a stable weld.
  • Softness: Being softer than steel, aluminum can easily burn through if the wrong technique is used.

Understanding these differences is the first step to achieving clean, strong welds.

Tools and Materials Needed

  • MIG or TIG welder (with AC capability for TIG)
  • Spool gun (for MIG) or pure tungsten electrode (for TIG)
  • 100% argon shielding gas
  • Stainless steel brush or dedicated aluminum wire brush
  • Aluminum filler rod (matched to your base alloy)
  • Clean rags and acetone for cleaning

How to Weld Aluminum (Step by Step)

1. Preparation is Key

  • Clean the surface: Remove dirt, grease, and oxide using a stainless steel wire brush or chemical cleaner.
  • Choose the right filler rod: For most general applications, ER4043 or ER5356 filler rods are common choices.
  • Set up proper shielding gas: 100% argon is standard for TIG and MIG aluminum welding.

2. Choosing the Welding Method

  • TIG (Tungsten Inert Gas) Welding: Best for precise, high-quality aluminum welds. It allows control over heat and is ideal for thin materials.
  • MIG (Metal Inert Gas) Welding: Faster than TIG, suitable for thicker aluminum sections, but requires a spool gun or push-pull system.
  • Stick Welding: Rarely used for aluminum, but possible with the right electrodes.

3. Welding Process

  • Maintain steady travel speed to avoid overheating.
  • Use short welds to control heat build-up.
  • Keep a tight arc to ensure penetration without burn-through.
  • For TIG, use AC (alternating current) mode to break through the oxide layer.

How to Weld Aluminum to Aluminum

Welding aluminum to aluminum requires proper joint preparation and control over heat input. Here’s how it’s done:

  1. Clean Both Pieces: Remove oxide layers completely on both aluminum surfaces.
  2. Choose the Right Joint Type: Butt joints, lap joints, and corner joints work best.
  3. Use Proper Filler Metal: Match the filler to the aluminum grade being welded.
  4. Control Heat: Start with lower heat and gradually increase as needed to prevent warping.
  5. Weld in Sections: Tack weld first to hold alignment, then complete the weld in small passes.

This process is commonly used in fabrication shops for frames, panels, and structural aluminum components.

Troubleshooting Common Problems

  • Porosity (bubbles): Usually from contamination or moisture; re-clean and use dry filler rod and base material.
  • Cracking: Caused by rapid cooling or incorrect filler rod. Always allow the weld to cool slowly and select matching filler.
  • Burn-through: Use lower amperage for thin pieces, and keep your travel speed steady.

MIG vs TIG

mig vs tig

Quick Answer: MIG welding (GMAW) uses an automatically fed wire electrode — faster, easier, and more cost-effective for thick metals and structural work. TIG welding (GTAW) uses a non-consumable tungsten electrode with a manually fed filler rod — delivering superior precision and cleaner welds on thin or exotic materials where quality is non-negotiable.

1. How Each Process Works

MIG Welding (GMAW — Gas Metal Arc Welding)

A continuous consumable wire electrode feeds automatically through a welding gun. The arc melts both wire and base metal simultaneously. An inert shielding gas — typically 75% argon / 25% CO₂ — blankets the weld pool to prevent oxidation. One hand operates the gun; settings are dialled in on the machine.

TIG Welding (GTAW — Gas Tungsten Arc Welding)

A non-consumable tungsten electrode generates the arc. The welder manually feeds a separate filler rod into the molten pool with the other hand, while a foot pedal controls amperage in real time. Pure argon is the standard shielding gas. The result: exceptional control over heat input, bead shape, and penetration. The key mechanical difference is how filler metal enters the weld pool: automatically in MIG, manually in TIG. That single distinction drives most of the trade-offs in speed, skill, cost, and quality.

2. Side-by-Side Comparison

Use this table to quickly assess which process fits a given project.
Factor MIG (GMAW) TIG (GTAW) Edge
Speed High — continuous wire feed; long fast beads Slow — manual filler feeding limits travel speed MIG
Weld Quality Good — minor spatter, occasional inconsistency Excellent — no spatter, clean bead, minimal cleanup TIG
Ease of Learning Beginner-friendly; weeks to competence Advanced; months to years to master MIG
Material Thickness Best on 3 mm and thicker steel Best on thin sections (under 6 mm) Situational
Metal Types Steel, stainless, aluminum Almost any: titanium, magnesium, copper, alloys TIG
Weld Appearance Functional; post-weld cleanup may be needed Beautiful; stack-of-dimes bead, minimal grinding TIG
Equipment Cost $300–$1,500 CAD typical $700–$3,000+ CAD typical MIG
Labour Cost Lower — faster throughput, lower cost per bead Higher — slow process adds labour hours MIG
Skill Required Moderate — machine settings are the key skill High — two-hand + foot pedal coordination required MIG
Best Industries Automotive, construction, structural, manufacturing Aerospace, food service, medical, decorative Situational

3. MIG Welding — In Depth

How the Wire Feed Changes Everything

The automated wire feed is MIG’s defining advantage. Because the machine continuously delivers both electrode and filler metal, the welder focuses solely on torch angle, travel speed, and gun position — dramatically reducing mental load compared to TIG.

Where MIG Excels

MIG is the dominant choice for structural steel fabrication, automotive bodywork, farm equipment repair, heavy machinery, and construction. In Ontario shops, MIG handles the bulk of day-to-day production welding on carbon and stainless steel.

MIG Limitations

Inconsistent arc strength if settings are not properly calibrated can lead to porosity or burn-through on thin material (under 1.5 mm). Outdoors, wind disrupts the shielding gas envelope — which is why stick or flux-core welding is preferred for exposed site work.

Shielding Gas for MIG

The most common MIG blend in Ontario is C25 — 75% argon, 25% CO₂. CO₂ improves penetration and reduces porosity. Pure CO₂ is cheaper but produces more spatter. Tri-mix gases are used for stainless steel MIG to produce cleaner welds.

4. TIG Welding — In Depth

Precision as a Design Feature

The foot pedal amperage control is TIG’s secret weapon. A welder can modulate heat in real time — backing off at a tight corner to avoid burn-through, boosting at a gap to fill a cold joint. No other common arc process offers this level of dynamic heat control.

Where TIG Excels

TIG is the process of choice when the weld will be visible, load-critical on thin sections, or in contact with food or chemicals. Stainless steel kitchen equipment, aluminum bike frames, titanium aerospace brackets, decorative railings, and pipe welds requiring X-ray quality all call for TIG.

TIG on Aluminum

Aluminum TIG welding uses an AC (alternating current) arc, which provides a cleaning action that breaks up the hard aluminum oxide layer before each pass. This makes TIG the preferred process for aluminum in automotive, marine, and architectural fabrication — especially on thin sections.

Shielding Gas for TIG

TIG exclusively uses 100% argon for most metals. Adding CO₂ (as in MIG) would oxidize the tungsten electrode and contaminate the weld. Helium or argon/helium mixes are used for deeper penetration on thick copper or aluminum.

5. When to Choose Each Process

If a project ticks more boxes on one side of the table below, that is typically the right process.

Choose MIG When…Choose TIG When…
  • Material is 3 mm (⅛ in) or thicker
  • Fast throughput or high-volume production
  • Structural steel — beams, frames, gates
  • Budget or schedule is constrained
  • Automotive body panels or chassis repair
  • Farm or heavy equipment fabrication
  • Weld aesthetics are secondary to function
  • Intermediate-skill welder on the project
  • Material is thin (under 6 mm / ¼ in)
  • Metal is aluminum, titanium, or stainless steel
  • Weld will be visible — aesthetics matter
  • Food-grade or hygienic surfaces required
  • Aerospace, medical, or X-ray quality standard
  • Decorative railings, signage, or sculpture
  • Pipe root passes in critical pressure applications
  • Dissimilar metal joining is required

6. Cost Comparison

Equipment

A quality MIG welder for professional use costs $600–$2,000 CAD. An equivalent TIG machine runs $1,200–$4,000+. AC/DC TIG units for aluminum cost more still.

Consumables

MIG uses relatively inexpensive wire (~$15–$40/kg for ER70S-6) and standard contact tips. TIG uses tungsten electrodes (reusable but gradually consumed), argon gas, and separate filler rods — contributing to a higher cost-per-metre of finished weld.

Labour

Labour is usually the dominant cost factor. Because MIG deposits metal significantly faster, MIG labour costs per metre of weld are substantially lower. On a structural steel project this can be the deciding factor — TIG at that thickness offers no quality benefit over MIG.

7. Ontario & GTA Context

In Ontario, welders performing structural work must comply with CWB (Canadian Welding Bureau) certification standards. Mobile Welding Service operates with CWB-certified welders across Toronto, Mississauga, Brampton, Vaughan, Markham, Hamilton, and Burlington.

Ontario’s weather also influences process selection. Wind-exposed sites in the GTA make both MIG and TIG challenging without shielding. An experienced mobile welder will assess wind conditions and may use temporary shielding or switch to stick / flux-core for outdoor structural repairs.

For on-site work in the GTA, the most common scenario is MIG for structural and heavy repair, and TIG for stainless steel or aluminum in commercial kitchens, facilities, and custom fabrication. Our mobile units carry equipment for both processes.

Frequently Asked Questions

What is the main difference between MIG and TIG welding?

MIG (GMAW) automatically feeds a consumable wire electrode, making it fast and beginner-friendly. TIG (GTAW) uses a non-consumable tungsten electrode and requires the welder to hand-feed a separate filler rod — enabling far greater precision at the cost of speed and skill complexity.

Which is stronger — MIG or TIG welding?

Both processes can produce welds that match or exceed base-metal tensile strength. TIG is generally considered superior on thin materials due to precise arc control. Properly executed MIG welds on structural steel are equally strong — the construction and manufacturing industries rely on MIG for load-bearing work.

Which process is faster?

MIG is substantially faster. Continuous wire-feed allows long, uninterrupted beads at high deposition rates. TIG requires manually adjusting the filler rod after each dip, resulting in much lower deposition rates — acceptable for precision but impractical for high-volume production.

When should I use TIG instead of MIG?

Choose TIG for thin materials (under ¼ inch / 6 mm), exotic or reactive metals, food-grade equipment, visible decorative welds, aerospace applications, or any situation where weld appearance and zero contamination are critical. TIG is also specified for pipe root passes where X-ray quality is required.

Is MIG or TIG welding more expensive?

TIG costs more at every level: equipment (TIG machines run roughly double the cost of MIG), consumables (tungsten and filler rods cost more than wire), and labour (slower process means more hours per metre of weld). MIG is the cost-effective default for structural and production welding.

Can mobile welders do MIG and TIG on-site in Toronto and the GTA?

Yes. Mobile Welding Service carries both MIG and TIG equipment and serves all communities across Toronto, Mississauga, Brampton, Vaughan, Markham, Hamilton, Burlington, and surrounding GTA areas. Our CWB-certified welders assess each job and recommend the appropriate process before starting work.

Structural Welding in Construction - Why Strength Matters

The construction of structures would require varying sorts of welding materials. Below are few top reasons why stronger structural welding is important in construction:

  • Strength and Toughness for Durability: Welding not only makes strong joints but also makes them immune to corrosion and wear. Due to the strength that welds add to joints, they can endure even heavy loads and stresses in a harsh environment for a good number of years.
  • Flexible Design: Using structural welding, even more design is possible with a product. It allows complex shapes and joints to be achieved that are difficult or even impossible to replicate otherwise, e.g., with rivets or bolts. Yet, it allows for unique and impressive designs in terms of functionality and aesthetics.
  • Faster Construction: Building becomes faster through welding since the welded joints are often done faster than bolted connections. Consequently, welding might give the total cost savings of labor as well as time spent at the site.
  • Economical: It is cost-effective compared to the other ways to assemble structural parts. This method is cheaper because it requires only the initial outlay to procure the equipment.

Types of Structural Welding Processes

In construction, a variety of structural welding techniques are employed, each having unique uses and advantages. Some of the most used welding methods in the construction sector are listed below:

1. Shielded Metal Arc Welding (SMAW)

  • Versatile, that it may be used in steel construction to weld in steel and more; such is stick welding-SMAW.
  • It is a procedure using consumable stick electrodes wherein the flux covers them.
  • This generates an arc that melts the work and deposits the electrode.

2. Flux-Cored Arc Welding (FCAW)

FCAW is practically the same as GMAW except the flux-cored wire is employed instead of a solid wire. There are also fluxes enclosed in the wire, which allow the shield gas produced to effectively weld thicker materials. For outdoor construction work and projects needing high deposition rates, FCAW is particularly effective.

  • Some heavy structural steel
  • Often pipelines
  • Shipbuilding

3. Tungsten Inert Gas Welding (TIG)

TIG welding is a precise, high-quality welding process used for thin materials and intricate welds. It uses a tungsten electrode to create an arc and requires a filler material for the weld. While TIG welding is slower than other processes, it provides excellent control over the weld and is ideal for projects that demand high-quality finishes. TIG welding is often used in:

  • Aerospace applications
  • High-end structural welding
  • Decorative steelwork
