True. Contamination of cast aluminum is always a problem when welding. Oil, dirt, minerals from water, or whatever came into contact with the part needs to be dealt with. With this pan I pre-heated the crack with the tungsten tip on the tig torch. I then cleaned the oil smoke and do that over until the area is clean to weld.
