Although I do know the correct way to weld 6061 alum. to get max strength, does anyone know the best "cheat" method of welding it to retain the most strength? 6061-T6 is approx 45K tensile. After welding, the area around the weld is approx 15K tensile or 1/3 of it's original strength. Would one weld, then cool slowly or quench in water quickly? Possibly short quick beads to minimize heat affected zone? I have a lot of 6061 T6 on hand, and I'm looking to get the least softening at the weld area as possible. The very best procedure I know is to buy 6061 T0, weld, then heat treat to T6. So, what's a good "second best method"? Dixon
