Can aluminum be brazed, using a tig machine?
Matt
cj, I am welding small aluminum tubing 3/16 and being a beginner to aluminum I am having some trouble blowing out the weld joints. I thought if I could braze them I would need less heat but still be strong enough for its intended purpose.

A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none.

Something to try: preheat your tubing with propane. If your machine allows a change in Freq, dial it up to 150Hz or higher. Set your AC balance down to 65%. This will help reduce your heat effect and penetration a bit. And once your puddle starts, get off the PEDAL. Or, Bump along on/off the pedal making basically tacks of 2-3 dips. Then stop. Let cool a bit, then begin again. Thin aluminum is the Devil's Toy to weld for new welders.adksigns wrote:cj, I am welding small aluminum tubing 3/16 and being a beginner to aluminum I am having some trouble blowing out the weld joints.

Thank you, everyone, for your help.

Given that it's 3/16" OD and 0.035 wall, it can only be decorative.LtBadd wrote:Hello adksigns
