Copper-manganese alloy filler rod - for MIG welding ferrous and non-ferrous metals (OE 15.1.78)

摘要

The filler rod for arc welding ferrous and non-ferrous metals has the compn. (wt.%) 8.0-38.0 (14.0-38.0) Mn, 0.1-1.0 Si, 6.0-24.0 (6.0-18.0) Ni, 0.5-5.0 Fe, balance Cu, up to 5% Ni may be replaced by Co, Fe may be replaced partly by Cr, Al, Mo, Nb, W and Si, and wholly or partly by Ti, Li and Be. The filler rod may be used with 5.0-14.0% of a known Cu-Al filler rod which is molten in the liquid pool without arcing in the TIG or MIG or plasma arc welding method. For welding Cu-Ni- and Fe alloys, espec. iron castings.
