What is the primary purpose of the Gas Metal Arc Welding (GMAW) process?

The primary purpose of the Gas Metal Arc Welding (GMAW) process is to join metal parts using an electric arc. In GMAW, a continuous solid wire electrode is fed through a welding gun and melted by the electric arc formed between the electrode and the workpieces. This process allows for the fusion of the base metals, creating a strong and durable joint. GMAW is widely used in various industries due to its efficiency, versatility, and ability to weld different types of metals.

While cutting through metal surfaces, applying coatings, or cleaning surfaces are important processes in metalworking, they do not fall under the primary function of GMAW. The process is specifically designed for welding, which involves joining materials rather than separating or modifying them in the same context as the other options.
