Welding Information - Rolled Alloys, Inc.
SAW is an automatic process using spooled wire like GMAW/MIG, except the wire is larger diameter. 3/32” diameter is common for nickel alloys, but 1/16” and 1/8” diameter wires are also used. Instead of shielding the welding arc with the inert gas argon, in SAW a hopper drops granulated flux [like coarse sand] down, to melt in the arc and protect the weld puddle from oxidation.
