MIG Welding Solutions for Every Industry
MIG welding (GMAW) feeds a consumable wire electrode through a welding gun to produce fast, efficient welds on steel, aluminum, and other metals for production applications.
About MIG Welding
MIG welding, formally known as Gas Metal Arc Welding (GMAW), is a semi-automatic or automatic arc welding process that feeds a continuous solid or tubular wire electrode through a welding gun. A shielding gas (typically argon/CO2 mixture for steel, pure argon for aluminum) protects the weld pool. MIG welding is the most widely used industrial welding process due to its versatility, speed, and ease of automation. It is significantly faster than TIG welding and can be used on a wide range of material thicknesses from 24 gauge sheet metal to heavy structural plates. Robotic MIG welding is standard in automotive manufacturing and high-volume fabrication.

MIG Welding FAQ
Is MIG welding stronger than TIG welding?
Both processes can produce full-strength welds. The strength depends on proper technique, parameters, and filler metal — not the process itself. TIG often produces higher-quality welds with fewer defects, but a properly executed MIG weld is equally strong.
What gas is used for MIG welding?
For carbon steel, 75% argon / 25% CO2 (C25) is most common. Pure CO2 is cheaper but produces more spatter. For aluminum, pure argon is used. For stainless steel, tri-mix (helium/argon/CO2) or 98% argon / 2% CO2 is common.
Can MIG welding be used on aluminum?
Yes, MIG welding aluminum is common using a spool gun or push-pull gun system with pure argon shielding gas. It is faster than TIG welding aluminum and preferred for thicker sections and production environments.
What is the difference between MIG and flux-cored welding?
Standard MIG uses solid wire and external shielding gas. Flux-cored welding uses tubular wire with flux inside that generates its own shielding gas (self-shielded) or is used with external gas (dual-shielded). Flux-cored is better for outdoor use and thicker materials.
How fast is robotic MIG welding?
Robotic MIG welding achieves travel speeds of 30-80+ inches per minute, compared to 10-20 inches per minute for manual welding. Combined with consistent quality and minimal downtime, robotic MIG cells can be 3-5x more productive than manual operations.
