Solid welding wire for joining, refacing and repairing pure copper, copper-silicon, copper-manganese alloys and brass.
Also suitable for building up a copper layer on carbon steel, lowalloyed steel, cast iron and for joining copper to steel.
Welding CuSi2Mn (Wn° 2.1522), CuSi3Mn (Wn° 2.1525) and brass (Cu-Zn alloys).
Also suitable for joining galvanised steel, where the low working temperature helps to prevent zinc burnoff.
Suitable for Mig brazing of thin galvanized sheet metal.
Hardness: 80 - 100 HB
Shielding gas: argon (or Helium for thicker materials or for higher welding speeds.)
Weld thin beads in order to obtain a fast cooling rate of the deposited metal.
Preheat pure copper.
Weld CuSi castings without preheat and limit the interpass temperature to max. 70 °C (160 °F).
