A filler metal for the welding of steel and iron, copper and copper alloys, with and without surface finishing, which shows a good wetting and also a good flow for surface-treated base metals, which does not form any scales and any visible crusting and does not build up too much, thus has an insignificant pore formation and a comparatively insignificant splatter formation, has the following composition in percentage by weight: 0.01-2.5% Si, 0.1-0.4% Sn, 0.6-1.5% Mn, 0.005-0.020% P and/or 0.002-0.020% B, whereby P and B together are less than 0.020%, the remainder being copper, impurities Pb less than 0.02%, other impurities together less than 0.5%. |
