Phosphorus deoxidised Wires for welding copper base alloys. The alloy has a wide freezing range and therefore has sluggish flow characteristics which can be minimised by preheating where circumstances permit.
TYPICAL APPLICATION :
- These wires are used to weld a range of copper base alloys to themselves and to C-Mn steels or cast irons, and the repair and joining of castings.
- They are also suitable, if a low dilution is achieved, for weld overlaying to give a bearing surface and/or corrosion resistant layer on steel components, shafts etc. Tin bronzes (up to 10% tin and 0.5% Phosphorus): BS PB101-3, UNS 52100 etc. Gunmetals (but>5% Pb leaded types difficult): BS LG3, LG4, LPBI etc. Bell metal (Cu+20-25% tin).
- Brasses (Cu+40% zinc), manganese bronzes
Shielding gas: Argon : Pure Argon , He or Ar-He.
