How To Weld Aluminium Using Mig. MIG welding aluminum requires you to utilize forward welding direction using your forehand to provide push motion. How To Weld Aluminum With A Mig Welder Cleaning your aluminum and electrodes Before starting remember to clean the aluminum by applying a few droplets of solvent like acetone or use a wire brush.
If not youll need to do some research to know what thickness you can work with. Achieve the Best Quality When MIG Welding Aluminum. The recommended electrode angle of travel is 5 to 15 degrees.
Also make sure the filler is at a 10-degree angle from the tip of the torch.
If the angle falls within this range it will be much easier to control the molten pool. When welding aluminum you are dealing with a much softer metal. Hold your welder at a 10-degree angle and keep a regular distance 64 mm between the tungsten and the aluminum. This allows you to ensure that the shielding gas sufficiently shields the weld puddle.
