D127
Description:
D127 is a common manganese type surfacing welding consumable of low-hydrogen type coating, which is reverse-connected by DC.
use:
Used for surfacing welded wear low carbon steel, carbon steel and low alloy steel surfaces, such as axles, gears, walking drive wheels, mixer blades and so on.
