CLASSIFICATIONS: ENiCrMo10T1-4 per AWS A5.34

SelectAlloy 622-AP is a gas-shielded, flux cored, nickel-based electrode with a nominal weld metal composition of 21% chromium, 14% molybdenum, 3% tungsten with a nickel balance. This electrode is primarily utilized to weld Ni-Cr-Mo to itself or to other nickel-based alloys. SelectAlloy 622-AP is used for surfacing steel and for joining nickel-based alloys to steel.

APPLICATIONS:SelectAlloy 622-AP is designed to weld in offshore and marine environments, chemical and power generation equipment and petroleum refining. This premier electrode is also widely employed to clad steel when exceptional corrosion resistance is required.

DIAMETER: .045"

SHIELDING GAS: 75-80% Ar/balance CO2, 30-40 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Outstanding all position performance characteristics.
  • Delivers notably higher out-of-position deposition rates than solid wires or covered electrodes.
  • Flat, well washed beads achieved with minimal weaving.
  • Spatter is very low and slag peeling is exceptional, reducing cleanup time.
