The car body is cast iron, and the material of each car body is different. Theoretically, the covered electrode of J506 and 308 can be welded by hot welding, but in fact, due to the different materials of each body and the particularity of hot welding, it is difficult to guarantee a high success rate. However, the cast iron welding rod of WEWELDING777, which is widely used, can be used, but the yellow box called WE777 is filled with fakes, and there are too many fakes. Authentic is covered electrode nameplate with WEWELDING 777 anti-counterfeiting trademark, and its technology is welded by cold welding technology. Its main feature is that it is universal for body materials and has good crack resistance.

Characteristics of WEWELDING777 Special cast iron welding rod

WEWELDING777 has a special coating function, which can generate a gentle arc similar to a pulse in the welding process, and has little thermal impact on various cast iron substrates. Special pulsed arc can remove impurities on the surface of various cast irons, and even for the welding of oil-contaminated cast irons and long-term oil-immersed cast irons, it has good permeability, will not produce pores or inclusions, and the hardness of heat affected zone will not become very high. The formed weld welded by cold welding process has excellent crack resistance and can cope with various harsh substrate environments.

Application of WEWELDING777 Special cast iron welding rod

Suitable for omni-directional cold welding, it can weld almost all cast iron substrates, and it is easy to realize heterogeneous welding of cast iron and carbon steel, and solve the defects of matrix fracture, crack, wear and hole filling. After welding, it can be machined completely, and can be applied to various cast iron parts such as engine housing, cylinder head, frame, gear teeth of casting gears and so on in many occasions.
