What is a common welding process for joining sheet metal?

Resistance spot welding and gas metal arc welding (MIG) are both widely used processes for joining sheet metal due to their effectiveness and efficiency. Resistance spot welding is particularly suited for thin materials and offers rapid joining by creating localized heat through electrical resistance. It's commonly used in the automotive industry and for assembling electrical components. Gas metal arc welding, or MIG welding, utilizes a continuous wire feed and shielding gas to create a weld, making it versatile for various sheet metal thicknesses and types of metals. It allows for a clean and precise weld, which is essential when working with sheet metal applications.

The combination of these two methods provides welders with options depending on the specific requirements of the project, such as thickness, material type, and production speed. Their adaptation to various sheet metal applications underscores their importance in metal fabrication and manufacturing processes.
