  • What is Welding? - Types of Welding Processes

    However, fusion welding processes, such as gas welding, arc welding, and gas metal arc welding are used in a large number of industries. Gas welding is a process by which the two pieces of metal are locally heated to beyond their melting point, at which time they effectively become one piece of metal. This can be done with or without an alloy rod.
