How To Weld On Aluminum. In the forehand technique used for MIG welding aluminum the electrode will be pointed in the direction of travel. Firstly you need to get your flux-coated aluminum electrode ready prepare the base metal set the current and polarity on the welding machine right and start welding.
Getting the tubing hot enough may take 4 to 5 minutes. Achieve the Best Quality When MIG Welding Aluminum. Detailed weld settings are available in standard text books or from suppliers of the material or equipment and may depend on the detailed quality requirements and materials being used.
Types of Aluminum Welding.
Firstly you need to get your flux-coated aluminum electrode ready prepare the base metal set the current and polarity on the welding machine right and start welding. In the forehand technique used for MIG welding aluminum the electrode will be pointed in the direction of travel. When you get a puddle formed bump your amps to 25 and begin running beads around switching the can between welds. Aluminum oxide on the surface of the material melts at 3700 F while the base-material aluminum underneath will melt at 1200 F.
