NS-102 CopperFree™ is a low alloy, high strength solid filler metal containing 0.5% molybdenum to maintain hardness and strength following post weld heat treatment. The manganese and silicon assist in producing a smooth, uniform weld bead and help minimize spatter.

CHARACTERISTICS

NS-102 CopperFree™ provides the ultimate in flexibility to support your GMAW operations.

  • Cast of 35 in. (.88m) to 55 in. (1.3m) and Helix below 1 in. (25.4mm) improve feedability and provide accurate wire positioning.
  • Excellent mechanical properties
  • Manufactured according to ISO9001:2008 quality standards
  • Excellent arc starts, arc stability and feedability
  • Minimal spatter
  • No copper flaking
  • Moderate de-oxidizers
  • Excellent weld appearance and post weld cleaning

APPLICATIONS

ASTM A182, A217, A234 and A335 high temperature pipe, fittings, flanges and valves and A336 pressure vessel forgings

Applications needing strength after post weld heat treatment

All metal transfer modes of GMAW

Robotic, mechanized or semi-automatic welding

Best results when using 95-98% Argon/Balance Oxygen shielding gas

TYPICAL APPLICATION SHIELDING GAS BLENDS

100% CO2: ER80S-D2

75-95% Argon/Balance CO2

95-98% Argon/Balance O2 ER90S-D2

Flow Rate: 35-50 CFH

WELDING POSITIONS

All position welding is possible when using the correct shielding gas blends, welding process and welding parameters.

STORAGE

Welding wire should be stored in a dry, enclosed environment and in its originally-sealed package.
