A fusion welding method using an electric arc as a heat source is called arc welding. Can be divided into manual arc welding, submerged arc automatic welding and gas shielded welding.
The biggest advantage of manual automatic welding is that the equipment is simple, flexible and convenient to apply, wide in application, and can weld various welding positions and straight seams, ring seams and various curve welds. Especially suitable for welding in the case of constant operation and welding of short welds;
Submerged arc automatic welding has the characteristics of high productivity, good weld quality and good working conditions;
Gas shielded welding has the characteristics of good protection effect, stable arc and concentrated heat.
