MIG Welding Services in Ontario
High-speed MIG (GMAW) welding for steel, aluminum, and stainless steel. Production welding, prototype fabrication, and custom welded assemblies from our Brampton, ON shop.
Dependable Laser Works provides professional MIG welding services for industrial, automotive, manufacturing, and trucking clients across Ontario. MIG welding delivers high-strength, high-speed welds ideal for medium to high-volume fabrication, from structural components and equipment frames to custom assemblies. Because our MIG welders work alongside our laser cutting and bending, your parts move from flat sheet to finished weldment under one roof.

What Is MIG Welding?
MIG welding, short for metal inert gas welding and officially known as gas metal arc welding (GMAW), is a process in which an electric arc forms between a continuously fed wire electrode and the base metal. A shielding gas, typically argon, CO2, or a blend, flows through the welding nozzle to protect the molten weld pool from atmospheric contamination. GMAW welding is one of the most widely used processes in industrial fabrication because of its speed, versatility, and ability to produce strong, consistent welds across a wide range of metals and thicknesses.
High Speed
The continuously fed wire makes the MIG welding process significantly faster than TIG, which is ideal for production runs and high-volume fabrication.
High Strength
Deep-penetration welds suitable for structural and load-bearing applications.
Material Versatility
Mild steel, carbon steel, stainless steel, and aluminum, each welded with the correct wire and gas selection.
Lower Cost Per Part
Higher deposition rates and faster travel speed reduce labour cost per weld, which matters most at production quantities.
MIG Welding Process, Equipment and Technique
Good MIG welding is more than pulling a trigger. Every job in our shop starts with matching the setup to the material.
Settings dialed to the material. Our welders adjust MIG welding settings, including voltage, wire feed speed, and travel speed, to the specific alloy and thickness on the table. The settings that produce a sound weld on 1/4 inch steel will burn through a 22 gauge sheet, and experience is what closes that gap.
Wire and gas selected per job. MIG welding wire and shielding gas are chosen as a pair. Solid steel wire with a CO2-argon blend for structural steel, stainless wire with tri-mix gas for 304 and 316, and aluminum wire with pure argon for 6061 and 5052. The wrong MIG welding gas produces porosity that no amount of skill can hide.
Equipment maintained for consistency. Industrial MIG welding equipment only stays consistent when it is looked after. Clean liners, fresh contact tips, and clear nozzles keep the arc stable across an entire production run, so part one hundred welds like part one.
Technique matched to the joint. Push versus pull, stringer versus weave, and torch angle all change penetration and bead profile. Our welders apply the MIG welding technique each joint calls for rather than one habit applied to everything.
Materials We MIG Weld
Mild Steel and Carbon Steel
The most common application for MIG welding steel. Hot rolled, cold rolled, and structural material, ideal for frames, brackets, guards, and load-bearing components.
Stainless Steel
MIG welding stainless steel requires the right wire and gas blend, and we run both for 304 and 316 grades used in food service, HVAC, and industrial applications. Clean, strong welds on sheet and plate.
Aluminum
MIG welding aluminum demands proper feeding equipment and pure argon shielding. We weld 6061 and 5052 alloys for lightweight assemblies, truck bodies, enclosures, and structural components.
Integrated Metal Fabrication Systems
Dependable Laser Works integrates high-precision flat cutting, automated angular press forming, and high-speed MIG joinery under one roof to deliver seamless structural fabrications.
Laser Cutting
Fiber laser systems rapidly slice clean profiles out of steel, stainless, and aluminum, maintaining razor-sharp edge tolerances for hassle-free downstream assembly.
Brake Press
Multi-axis CNC press brakes form cut profiles into exact structural shapes, ensuring seamless seam alignments and optimal joint fit-up for rapid MIG welding.
MIG Welding Applications
MIG is the go-to process for any application where strength, speed, and volume matter:
- Structural frames and equipment bases
- Machine guards and safety enclosures
- Truck body components and fleet brackets
- Industrial brackets and mounting assemblies
- HVAC enclosures and ductwork assemblies
- Custom fabricated assemblies for manufacturers
- Prototype welded assemblies built from our own laser-cut MIG welding parts
- Exhaust components and automotive brackets
MIG Welding vs TIG Welding
Choosing the right process gets you the right result at the right cost. Here is how the two compare:
| Factor | MIG Welding | TIG Welding |
|---|---|---|
| Speed | Fast | Slower |
| Best for | Medium to high volume, structural | Precision, thin gauge, cosmetic welds |
| Materials | Steel, stainless, aluminum | Stainless, aluminum, thin sheet |
| Weld appearance | Good, functional | Excellent, clean precise bead |
| Cost per part | Lower | Higher |
| Production volume | Medium to high | Low to medium |

Why Choose Dependable Laser Works for MIG Welding
Production Consistency
A skilled MIG welder plus maintained equipment plus programmed fixturing means the last part in a run matches the first.
Cut, Bend, and Weld in One Shop
Most weldments start as laser-cut blanks. Ours never leave the building between processes, so fit-up stays tight and lead times stay short.
Three Materials Done Properly
Steel, stainless, and aluminum each get their own wire, gas, and settings. No shortcuts and no one-setup-fits-all welding.
Prototype to Production
One test weldment or a recurring monthly order, built on the same equipment to the same standard.
Local and Responsive
Based in Brampton, serving the GTA and all of Ontario. Visit the shop, inspect first articles, and talk to the people holding the torch.

FAQs MIG Welding
What is MIG welding used for?
MIG welding is used for structural fabrication, production welding, automotive parts, truck body components, machine frames, and any application where strong, high-speed welds are required.
What metals can you MIG weld?
We MIG weld mild steel, carbon steel, stainless steel in grades 304 and 316, and aluminum in 6061 and 5052 alloys.
What is GMAW welding?
GMAW stands for gas metal arc welding, the official technical name for MIG welding. The two terms describe the same process.
How is MIG welding different from TIG welding?
MIG is faster and better suited to production and structural applications. TIG is slower but delivers cleaner, more precise welds, which makes it the choice for thin gauge and cosmetic work.
Can you MIG weld aluminum?
Yes. We MIG weld 6061 and 5052 aluminum using dedicated feeding equipment and pure argon shielding gas for clean, strong aluminum welds.
Can you MIG weld cast iron?
Cast iron is generally a poor match for the MIG process because of its carbon content and cracking risk, and it is not a material we stock or fabricate. Our MIG welding covers steel, stainless steel, and aluminum. If your project involves cast iron, we are happy to point you in the right direction.
Do I need to know welding settings or gas types to order?
No. Send your drawing, material, and thickness, and our welders handle wire selection, shielding gas, and machine settings. That is our job, not yours.
Do you offer both prototype and production MIG welding?
Yes. We handle one-off prototype welding as well as medium and high-volume production runs, with no minimum order.
What do you need to quote a MIG welding job?
Email your drawing with weld callouts, material, and quantity to laserworks@dependable.ca, or call 647-504-5956 and describe the job. Photos help for repair or replication work.
