How can argon welding be used to weld copper material? What do you need to have? Is the argon arc welding machine OK?
Because of its fast heat dissipation, it needs preheating before welding and filling with high current. It is better to weld with AC and DC welding machines, such as stainless steel, copper, aluminium, tin, copper and nickel, etc. the direct current welding of ferrous metals, that is, ordinary steel pipes, steel plates, etc., is not required.
Gas welding speed is relatively good brass, molding difficult aspect. Red copper or nickel copper alloy can be welded by argon arc. Welding wire is right. No brass welding wire can be used.
The manual argon arc welding of brass can be made of standard brass wire: wire 221, wire 222 and wire 224, and it can also be used as filling material with the same material as base metal.Welding can be done by DC or AC. When welding by alternating current, the evaporation of zinc is lighter than that of direct current. Usually, there is no need to preheat before welding. Only when the thickness of the plate is relatively large can it be preheated. Welding speed should be as fast as possible. The weldment shall be annealed at 300~400 degrees after welding to eliminate the welding stress so as to prevent the weldment from cracking during use.No other things, general argon arc welding machine can be.
