How To Weld With Aluminum. For the 14 6mm lap joint shown in the video the mig joint took 45 secondsthe tig weld took 60 seconds. Welding aluminum requires a thorough understanding of the tig welding process and also requires a tig torch.
However soldering is the best method to weld aluminum and copper. Aluminum should be thoroughly cleaned prior to welding including the removal of any lubricants from the material. Getting the tubing hot enough may take 4.
Lets run through how you can stick weld aluminum.
Aluminum conducts heat six times faster than steel and has great thermal conductivity. Aluminum will start to melt at 1200deg Fahrenheit but the brazing rod will melt at around 700deg so we want to get the aluminum hot enough to melt the rod without melting the tubing. 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. Use hotter settings in terms of amperage and.
