Weave pattern for Tig aluminum

admin

I went to a buddies shop today and noticed he was welding A large piece of aluminum tube to a Flat plate.... What caught my eye was He weaved the weld like he was welding a pipe joint...Even though the joint was well fit with no gaps....I wouldn't have welded that joint like that, you guys think It was over kill?  Miller Dynasty 350Twenty Six HammersThree Crow BarsBig Rock

Reply:Hello B_C, depending upon the intent and use of this piece it may or not be detrimental. If he is attempting to maintain maximum strength in the as-welded condition the wide weaving is not for the better and especially if it is a heat-treated alloy such as 6061T-6. But even at that, if the part is a stand for an umbrella or something like that it probably isn't going to result in the end of his world. However, if it's purpose is one of importance the technique would not be the best choice as you said. Best regards, Allanaevald

Reply:Hello MikeGyver, I could agree with that if the plan was to possibly heat-treat after the welding was performed but I kinda doubt that is going to be the plan in this case. Just my $.02. Best regards, Allanaevald

Reply:shovelon,I sure wish I'd have had your Dynasty700 (and your expertise on setting it and welding with it) when I did this heavy aluminum job.   I had to do it with a Syncrowave 250.  Even with some serious preheat from a rosebud about half way thru I smoked the 50 amp dryer plug on the machine right off the wall.  It melted and failed in a pretty spectacular fashion.   Had to stop and rob a plug off another machine in order to keep going and finish.
