Jan 27, 2016· Let the welded metal cool and remove unwanted slag by chipping it away. This will give the aluminum time to cool down between welds, and prevent too much heat from building up in the aluminum. As the aluminum heats up, the amperage will need to be reduced. Gas metalarc (MIG) Welding. MIG welding was developed in the 1940''s.
Slag (flux) removal can vary considerably depending on the rod used, technique, and the phase of the moon. Ok, just kidding about the moon. 6011 rods leave a slag that is thin and doesn''t just pop off like 7018 which will almost, and in some instances, remove itself. I''ve worn out a lot of wire brushes cleaning up welds.
