Submerged arc welding is mainly used for steel structural parts such as steel structural parts of bridges, H-beams of bridges, and girders of H-shaped structures. Gas shielded welding: argon arc welding, carbon dioxide protection welding, welding under the protection of the gas will not oxidize, welding firmly, can weld non-ferrous metals, weldable thin materials. Laser welder: Solderable leads inside the transistor. Butt welding machine: The cable factory mainly welds the iron wire and other objects on the anchor. Can be connected to the Yuan Steel. Multifunctional welding machine. Spot welding. Butt welder. Bolt welder. Carbon dioxide ammonia gas welding machine.
