RA Waspaloy
Welding is difficult, and best performed on material in the solution annealed condition. Limit currents and the size of the fusion zone. Rapid cooling from welding is necessary to minimize aging stresses. Copper backup bars or water cooled fixtures are desirable. After welding, the fabrication should be solution treated, using rapid heating and cooling rates through the aging range. Follow anneal by stabilization and aging treatments.
A typical heat treatment is a solution heat treat at 1825°F for 2 hours, air cool. Stabilize heat treat at 1550°F for 4 hours, air cool. Precipitation heat treat at 1400°F for 16 hours, air cool.
