There are two types of stainless steel electrodes: Ti CA type and low hydrogen type. DC power supply should be used as far as possible for welding current, which is helpful to overcome redness and shallow melting depth of welding rod.

Flux cored wire gas welding (fcaw-g) is a widely used welding process. It is widely used in heavy manufacturing, construction, shipbuilding, marine facilities and other industries of low carbon steel, low alloy steel and other alloy materials welding.

With the development of iron and steel, petrochemical, ship and electric power industry, the welding structure tends to be large-scale, large capacity and high parameters. Some of them are still working in low temperature, cryogenic, corrosive media and other environments.

In the welding process, the movement of welding rod relative to the weld is called moving rod. The movement of welding rod includes three actions: feeding along the axis of welding rod, longitudinal movement and transverse swing in the direction of no welding seam axis.
