摘要
Method of arc welding or beam welding/soldering of workpieces (A) of steel, cast iron, Ni, Cd, Be, Ti, Mo, Mg, Al, Cu, Pb, Zn, Sn, hard metal and their alloys to workpieces (B) of the same metals and their alloys, where the A and B workpieces, which can be the same or different metals, are brought into contact with molten metal alloying additives involving:(a) positioning of the workpieces, (b) melting of metal alloying additives containing SnZn, SnAg, SnZnAg, SnCu, SnCuAg, SnZnCu or SnZnCuAg alloy, (c) application of the melted metal alloying additives to the contacting sites or some of them between the positioned workpieces, where steps (b) and (c) immediately follow each other. An independent claim is included for a welding wire of diameter 0.8-3.2 mm as an additional workpiece material comprising Sn-based alloy containing Zn and/or Cu and/or Ag.
