1, the welding between the sheet and the sheet. Generally use manual welding and automated welding, including the butt end of the welding, the center penetrate fusion welding, the center perforation fusion welding four processes method.
2, wire and Welding Wire. Generally use manual welding and semi-automatic welding, including wire and wire butt, cross welding, the parallel lap welding, Types Of Welding Electrode four process method.
3, the metal wire and the bulk element welding. Can be successfully achieved using laser welding the wire with the connection of the block member, the block-size of the element can be arbitrarily. The geometric dimensions of the filiform elements in the welding should be noted.
4, the different metals are welded. Welding different types of metal be possible to solve the weldability and solderability parameter range, laser welding between different materials, only certain combinations of materials.
Massive objects repair welding. Laser welding using laser melting deposited onto the substrate, generally suitable for the molds and other products of the patch.
