What welding process uses a resistive heating system to achieve metal deposition?

The welding process that uses a resistive heating system for metal deposition is known as Resistance Welding. In this process, electrical resistance is utilized to generate heat at the interface of the materials being joined, which causes them to melt and fuse together. This method is commonly used for spot welding and seam welding, particularly in the automotive industry for joining sheet metal components. The efficiency and speed of resistance welding make it suitable for high-volume production.
