Aluminum Die

Repair and change the design of Aluminum to match patterns and dies. The section to be worked is cleaned by filling and grinding, then tinned by heating the Aluminum to a temperature that will melt the solder stick rubbing the surface. When tinning, the Alumite™ stick should ALWAYS be kept out of the flame. Pre-heating the entire match plate of the die to approximately 600⁰F facilitates this procedure.

Zinc Casting

Remove any plating, natural oxide, or foreign matter from the surfaces to be joined. “V” out the fracture and set up the job solidly. Use a #1 or #2 tip to preheat the area surrounding the fracture. The weld is then made by heating the fracture directly with a neutral flame until the surface of the base metal can be broken by touching it with the Alumite™ rod.

KEEP THE ROD AWAY FROM THE FLAME AS MUCH AS POSSIBLE WHEN STARTING TO WELD. Continue welding the fracture by puddling the solder in the base metal. Never plunge into cool water. Finish as desired.

White Metal

Clean plating and scale from the surface to be welded. “V” out the fracture and set up the job solidly. Preheat generally with a neutral or acetylene flame. Heat directly until the parent metal begins to melt, and then dip the solder rod in and out of the molten puddle to the desired build up. Never plunge into water to cool. Finish as desired.

Stripped Threads

Drill the old threads out over size, so that when the new fillet is added all the drilling and tapping will be done in Alumite™. This will make it easier to work with and will increase strength. After drilling, heat the base metal from the bottom of the hole up. Tin the rod into the wall of the hole, beginning at the bottom and working up. Fill the hole, cool, drill and tap as needed.
