process for inert gas welding or white inert gas welding of workpieces, and, wire

摘要

"PROCESS FOR INERT GAS WELDING OR WHITE GAS WELDING PARTS, AND WIRE". The invention relates to a process for welding inert gas welding inert gas welding workpieces (A) made of steel, aluminum, magnesium, copper or their alloys with workpieces (B) made of steel, aluminum, magnesium , copper or their alloys using an additional molten alloy, workpieces (A) and (B) being made of identical or different metals or alloys. The inventive process is characterized by the following steps: a) the workpieces to be connected are contacted edge to edge or overlapping; b) the additional metal alloy containing a Zn / Al alloy is fused; c) the additional cast alloy is applied to the contact points or partial areas of the contact points of the contacted workpieces; d) the connected workpieces are cooled. Steps b) and c) are performed immediately or one after the other while at least steps b) and c) are performed using an inert gas. The invention further relates to a wire that is used in said process.
