How To Welding A Aluminum. When the layer is done both metals can be arc welded. The recommended electrode angle of travel is 5 to 15 degrees.
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. Use DC reverse polarity the electrode will be positive while the base plate is negative. They can tune the power for thin aluminum foils as well as micromachining.
You can weld on aluminum foil with the use of an arc or spot weld.
The coating can be achieved through dip coating or by brazing the aluminum on the steels surface. Use DC reverse polarity the electrode will be positive while the base plate is negative. Tips for MIG welding. The hydrogen forms bubbles that become trapped in the metal leading to porosity.
