what is iron ore powder used in flux for welding electrodes

Welding Electrodes Iron Powder Manufacturers and

Using iron powder as an additive for electrode coatings or cored wires has several advantages including higher efficiency as well as improved welding characteristics and weld metal quality. In low and high-alloyed electrodes, iron powder is partly or entirely replaced by different metal and ferroalloy powders.

Iron Powder for Welding Acme Inter

2019-7-31  By adding iron powder to the welding electrode coating, it can be made thicker without any increase in the content of slag builders. This reduces raw material costs and improves energy utilization. Iron powder in the coating has a cooling effect on core wire, as the preheating of iron particles dissipates the generated heat.
