How Aluminium Welding Is Done. You can use MIG wire as a filler and then start at 20 amps. Preheat The Work Piece Another way to help prevent weld deformities is to preheat the workpiece prior to welding it.
To weld aluminum operators must take care to clean the base material and remove any aluminum oxide and hydrocarbon contamination from oils or cutting solvents. To weld aluminum clamp the aluminum pieces together tightly and use a propane torch to preheat them to a temperature between 300F and 400F. Then set the amperage of your welder aim at the aluminum pieces and press the button on the torch.
There are two main phases.
To weld aluminum operators must take care to clean the base material and remove any aluminum oxide and hydrocarbon contamination from oils or cutting solvents. You can weld on aluminum foil with the use of an arc or spot weld. They can tune the power for thin aluminum foils as well as micromachining. Ad Find China Manufacturers Of Aluminum Welding.
