Welding Materials (Welding Rods) that are incompatible for Anodizing
Hello Finishing.com'ers,
OK, so we have a Customer who is experiencing some issues when we Hard Ano their Aluminum parts with the following attributes.
#4130/#5052/#6061/#7075 type(s).
We are speculating the Customer is using Welding rods that are incompatible with the Hard Ano process.
Is anyone aware of a chart that shows what you can, & can not use for welding rods on aforementioned parts that are going to be Hard Ano'd.
Many Thanks in Advance !

I've found that 5356 works fairly well. However, there will always be a color difference between the weld, and the aluminum. Also, you can always expect to see a "halo" effect around the weld. Your best bet, would be to dye the work if color is consistency is a concern, but again, there will almost always be a difference.
