MIG Welding Services

For your toughest welding jobs, Fitchburg Welding Company can deliver the precision, speed, and consistent quality you need with Metal Inert Gas (MIG) welding.

This popular and versatile welding method is widely used in industrial production, auto manufacturing, and aerospace applications. It is suitable for both thick and thin materials, which may include steel, stainless steel, and carbon steel. MIG welding (along with TIG welding) is also an option for welding non-ferrous metals such as aluminum.

This method can achieve high metal deposition rates, making it very productive, particularly when controlled by an expert MIG welder.

The MIG Welding Process

In the MIG welding process, we use a consumable solid electrode. As the electrode melts to join the workpieces, more wire is continuously fed through the welding gun, keeping the process efficient.

As a type of Gas Metal Arc Welding, the MIG welding process also utilizes an external source of shielding gas, which is fed through the welding gun to protect the weld pool from atmospheric pollutants. These gases help prevent spatter while producing high-quality welds without any slag, so very little clean-up is needed. Argon and helium are typically used as shielding gases, but the choice is dependent on the material being welded as well as the requirements of your project. When MIG welding stainless steel, for example, we use pure argon or a tri-mix gas of argon, helium, and carbon dioxide to prevent mechanical damage as well as contamination.

Our MIG Welding Equipment

Fitchburg maintains a lineup of top-quality equipment for MIG welding, allowing us to ensure strong, consistent welds on large-scale projects. We use machines from Lincoln Electric, Miller, Cobramatic, and Hobart, including:

  • Weld positioners with adjustable height, 135° tilt, 360° rotation, and capacity up to 350,000 lbs.
  • 60,000 lb. turning roll
  • 40,000 lb. turntables
  • Fully automatic 3-axis manipulator / welding cell
  • 60″ x 60″ welding manipulator

A One-Stop Shop for Industrial Welding Services

At Fitchburg Welding, MIG welding is only one of our comprehensive capabilities. Before welding, we cut and bevel your material and assemble all parts. After welding, we perform stress relief treatments to produce stronger joints, and magnetic particle testing and other nondestructive testing methods are used to ensure welds are free of internal voids. Shotblasting is used to remove rust and prep the surface for painting, and finally, we apply paint or coatings to your specifications. Fitchburg Welding is ISO 9001 certified for welding and fabrication services.
