RFQs: Filler wire, UNS no W86333 or N06333* or Metrode Thermet 22H or equivalent

Details

RA333 weld fillers are necessary to ensure that the weld joint has the same strength and oxidation resistance as the RA333 base metal in the fabrication. RA333 plate, sheet and bar is welded with matching chemistry RA333 bare filler wire (spooled and straight lengths) and with RA333-70-16 AC/DC Titania covered electrodes. These specialty weld fillers are not included in AWS specifications. The chemistry of the bare wire meets UNS N06333*, and that of the covered electrodes UNS W86333.

A small amount, no more than 1%, of CO2 will help stabilize the arc. 100% argon may be used, but the welder will find it less satisfactory. ** Short-circuiting transfer usually calls for a higher helium level. Some gas mixtures which have been used include: 90% helium 7 ½% argon 2 ½% CO2; 81% argon 18% helium 1%CO2; and 66% argon 33% helium 1% CO2 Gas Tungsten Arc Welding (TIG), 2% Thoriated Tungsten Electrode Base Metal Thickness Electrode Diameter Wire Diameter Current (DCSP), Amps Voltage, Volts Shielding Gas 1/16” to 1/8” 3/32” 1/16” or 3/32” 50-90 12 Argon (100%)*** 1/8” to ¼” 3/32” to 1/8” 3/32” or 1/8” 70-120 12 Argon (100%)*** ¼” to ½” 3/32” to 1/8” 3/32” or 1/8” 100-150 12 Argon (100%)***
