All You Need To Know About Welding Anodized Aluminum ...

If the aluminum parts you need to weld have already been anodized, this wont be an option. Another alternative is to use a sanding or grinding disc and grind away the anodized layer in the welding area. The more accurately you can grind the area the better the result for the cosmetics of the finished piece. Even with careful processing, you may still find that the result is not aesthetically appealing. When neither of the above options is suitable, it is possible to weld the aluminum ...
