Boron carbide wear-resistant electrode is most suitable for surface strengthening surfacing of mechanical parts with strong abrasive wear under medium impact. The welding core is H08 series low carbon steel, and the coating is made of Cr, Ni, B, Mn, Mo, Ti and other mineral and chemical raw materials to improve the welding performance. The characteristics are: the coating is added with a large amount of boron carbide and a small amount of tungsten, vanadium, niobium, rare earth alloy elements and a variety of alloy element additives to improve the welding process performance, and the weight coefficient of coating is 50 It can be used in both AC and DC welding machines. The hardness of hardfacing layer can reach hrc65-70, and the wear resistance is 17.38 times of that of quenched 65Mn steel.

Scope of application:

It is suitable for surfacing welding of middle trough of scraper conveyor, blade of water turbine, bell of blast furnace, blade of screw feeder, drill pipe, auger of brick extruding machine, bucket tooth of excavator and pushing plate of coking plant.

Reference current:

Φ3.2 Φ4.0 Φ5.0

90－120A 160－190A 190-220A

matters needing attention:

1. Before welding, the sundries on the base metal surface must be cleaned up.

2. Small current should be used to prevent arc crack.
