Metal inert gas (MIG) welding is a type of arc welding that joins metal workpieces using an electric current, a consumable wire electrode, and an inert shielding gas such as helium or argon. The MIG welding process offers many advantages, making it a popular method for a wide range of applications and industries. Here, we will describe how MIG welding works, how it’s used, and its many unique benefits. 

What Is MIG Welding?

Inert gas welding

MIG welding, also known as gas metal arc welding (GMAW), uses an adjustable, continuously fed solid wire electrode to create welded joints. This versatile and easily automated welding method only requires the welder to guide the welding gun along the fusion point at the proper orientation and position. An electric arc forms between the workpiece and the electrode, which generates enough heat to melt and join the metals. 

How Is MIG Welding Used?

MIG welding utilizes an electrical current from a non-consumable or consumable solid wire electrode. As the electrical current generates heat, the filler materials melt to join two or more metal workpieces. In many cases, the filler material doubles as the electrode. This type of arc welding can be performed manually by a trained technician, or the process can be automated through moving equipment to ensure proper positioning and orientation. 

Benefits of MIG Welding

Commonly used for welding steel materials, MIG welding is versatile, relatively fast, and easy to control, making it a popular welding technique for various applications. Other key benefits of MIG welding include:

production welding

  • Speed. Compared to other welding methods such as TIG welding, MIG welding offers faster process speeds. 
  • Automated or manual. MIG welding units can be fully or partially automated, or they can be entirely manual based on the needs of each individual project.
  • Ease of Use. MIG welding, though it requires a consumable electrode or filler material, is simple and easy to control. It also offers easy cleanup and a lack of chipping. 
  • Versatility. MIG welding can be used with stainless steel and multiple other materials. This technique is also versatile in terms of weld position and joint thickness. 
  • Environmentally friendly. The wire electrodes are fully consumed for minimal product waste, making MIG welding more environmentally friendly than alternative methods.
