The role of the filler material in GMA (MIG) welding

The correct answer is B) Electrode wire.

When it comes to Gas Metal Arc (GMA) welding, also known as MIG welding, the filler material plays a crucial role in the welding process. The filler material, which is in the form of electrode wire, is used to create the weld joint between the base metals being welded.

The electrode wire is continuously fed through the welding gun and serves as both the filler material and the electrode in GMA welding. As the welding arc is established, the electrode wire is melted and fused with the base metal, creating a strong and durable weld joint.

This process allows for precision and control in joining metals, making GMA (MIG) welding a popular choice for various industries. Understanding the role of the filler material is essential for achieving high-quality welds in GMA welding applications.
