GMAW, or MIG welding, is a welding process that uses a continuous wire electrode and a shielding gas to produce a weld. It is commonly used for applications such as automotive manufacturing, steel construction, and other high-volume industries. GMAW provides high welding speed and excellent results in a variety of metals.

Advantages:

• Faster welding speed
• No slag formation
• More versatility with thicker materials
• Less need for skilled operators compared to other welding types

Limitations:

• More spatter than TIG welding
• Poor weld appearance
• Less penetration on thicker materials

Electrodes:
