Tig Welding Different Thickness Aluminum. Set process control to TIG. It additionally includes Infinite Amperage Control that gives a more extensive working extent and better control of the weld.
Light gauge metals less than 116 16mm thick should always be welded with DCSP using argon gas. Many other processes of course can join aluminum but in the lighter gauges the most applicable process is TIG. Although many metals are TIG welded the metal most frequently associated with the process is aluminum especially with metals of a smaller thickness.
4 It sounds as if you are welding in the flat position.
They are known as 4043 and 5356 alloy. Set process control to TIG. Todays video is on tig welding thin aluminumnot paper thin like a pneumatic duct on a jet but040 or 1mm. When TIG welding different thickness parts say for example in a lap joint of a piece of 316 flat bar to a14 ga 080square tube mild steel or ss parts other would be a joint of small tube dia to solid rod like the one in the tig finger video what would be the guideline for setup amperage tungsten dia rod dia and most important how wide the bead has to be.
