Welding technology is the operation method of using welding materials to connect two or more base materials into a whole under high temperature or high pressure conditions.
Welding technology is mainly applied to metal base materials, commonly used include arc welding, argon arc welding, CO2 shielded welding, oxygen acetylene welding, laser welding, electroslag pressure welding, and other non-metallic materials such as plastics can also be welded.
