O/T Welding Aluminuim

[JS]

If the part is not to big you can try submerging the majority of the part in water, leaving the water level about an inch below the welding area.

In order to weld this you are going to need as big a torch and tungsten elecrode as you can find, at least a 1/8 preferrably 3/16 with plenty of amperage. The reason you want the big tungsten is because you are trying to overcome the abnormal heatsink that you made and you will experience tungsten spitting in the weld if you do not use a large size tungsten. If you can lay a nice weld down you will have minimum distortion. I also use a 75% helium 25% argon mix when doing this. That will create a much hotter arc. I have been heliarc welding for 30 years and have save alot of parts this way.
