1. When the size of copper parts is relatively small and the structure is relatively simple, it is suitable for flame brazing or high-frequency brazing. Brazing filler metal can be brass or phosphor copper or silver phosphor copper.
Second, when the size of copper parts is relatively large and the structure is relatively complex, the following materials and equipment are selected for welding.
Selection of welding materials and welding equipment for argon arc welding of copper alloy
1) When the copper alloy matrix is copper, Viotin copper argon arc welding wire is selected for welding, and argon arc welding with DC function is selected for the equipment.
2) When the matrix of copper alloy is brass, Viotin brass argon arc welding wire is selected for welding, and it is emphasized that Viotin brass argon arc welding wire is a special welding wire for argon arc welding, not a brass gas welding wire. It must be clear that the welding equipment should be AC argon arc welding machine, and DC argon arc welding machine can be used without AC argon arc welding machine.
3) When the copper alloy needs dissimilar welding with iron, stainless steel and alloy steel, Viotin brass argon arc welding wire is used to bias the welding angle to one side of the copper alloy (supplement: if small pieces of dissimilar metal copper are welded with stainless steel, Goldin Viotin 203 welding or WEWELDING46 welding wire can also be used instead of silver welding).
4) When the copper alloy is large in size and copper matrix, high-power mechanical welding of Viodine WSME500 or double-pulse gas shielded welding of Viodine MIG500 can be selected. The welding wire is large-diameter straight TIG welding or 1.2 wire wound open welding, and the welding wire is also copper argon arc welding.
5) When the copper alloy is large in size and brass matrix, high-power mechanical welding of Viotin WSME500 or double-pulse gas shielded welding of Viotin MIG500 can be selected. The welding wire is large-diameter straight TIG welding or 1.2 specification open-wound welding, and the welding wire is also welded with Viotin brass argon arc welding wire.
