Does argon arc welding thick material need no welding wire?
Of course not. Argon arc welding is only suitable for thin parts.
No, the seam will sag, that is, the meat is missing.
Argon arc welding is not like welding, welding electrode itself is filling material, argon arc welding is no filling material. Argon arc welding stainless steel without welding wire is formed by melting the base metal. Such as two stainless steel butt welding wire, in no case, two pieces of plate must be no gap, when the tungsten needle alignment weld produced high current that produce high temperature, the two panels are also melting, loosen the gun switch after the melting of stainless steel water condenses together welded together, if we must have with the wire.Summary: no welding wire welding workpiece can solder together must leave, if even only 0.5mm are difficult to weld, first after welding, the welding, the welding speed should be uniform, without wires, not large current about 20A, from the middle to both sides welding. After welding, the main point of non deformation is that the plate should be docked and added at least 1 centimeters a point. The copper lining under the condition plate is best, and the weldment can be placed on the platform or made as a fixture. Speed must be fast, the more slowly, the more deformation.
