What is flux-cored arc welding?
Flux-cored wire arc welding is a welding method that uses the arc between flux-cored wire and workpiece to heat, and its English name is simply FCAW. Under the actio...
The primary function of welding shielding gases is to isolate the weld pool from the atmosphere, stabilize the arc, control penetration depth, and enhance overall weld quality. Conversely, select...
During fusion welding, under the action of the welding heat source, the liquid metal part with a certain geometric shape formed on the weldment by the molten electrode metal and the partially molte...
