Personnel engaged in welding technology-related work are called "welders". Welders belong to the category of mechanical thermal processing among mechanical manufacturing and processing personnel, and mainly operate welding and gas cutting equipment to weld or cut metal workpieces. Welding technology is widely used in aviation, nuclear industry, shipbuilding, construction and machinery manufacturing and other industrial sectors, and many enterprises give welders generous welfare treatment.
Welders are divided into two welding technologies, argon arc welding, argon arc welding and electric welding.
