ALUMINUM WELDING WITH PROFESSIONALS
Our pal, general automotive fabrication expert Rob Bonney, is a selfproclaimed “decent TIG welder.” Here he shows some fundamentals that we have already screwed up: the “pencil” grind on the tungsten, tungsten stick-out less than the diameter of the opening of the cup, and proper torch angle for weld-
ing a 90 like this. Also, he has the ground clamped directly to the aluminum and both pieces of aluminum are firmly held in place. Bonney also frequently uses Silicon Bronze rod to TIG-braze thin steel sheetmetal on bodywork. This method is not as structurally strong as TIG-welding steel but yields great results when modifying body parts.
