  • Electrode application range is wide, can realize a variety of materials, a variety of profiles and a variety of joint forms of welding. (1) Welding between low carbon steel, low alloy steel, medium carbon steel, alloy steel and other metal materials or dissimilar metal materials can be achieved. The weld has good comprehensive mechanical properties, and the tensile strength can reach more than 400MPa. ⑵ Can realize the welding of large plate, steel frame, plate – tube, rod – rod, tube – tube and other profiles. ⑶, can realize docking, Angle, lap, T joint and other joint forms of welding. ⑷ mainly suitable for flat welding.(5) it can surfacing the parts of wear failure, so as to obtain the surface surfacing layer with melting depth, smooth surface and excellent performance. ⑹ It can be realized that no bevel 1 ~ 6mm thick metal sheet single-side welding double-side molding.
