How does chemical conversion coating effect welding? We have a 5052-H34 large cabinet (6ft) that will be in an out door enviroment. do i need to weld the parts prior to finish?
Hi there, we checked with our team, and they had a couple points: -You would want to weld before chem filming, because the process of welding (and grinding the welds so they're smooth, etc) would remove the chem film coverage from the welded areas. This would increase the likelihood of corrosion for those areas that were welded. -However, one important note is that our chem film tanks can accommodate 43.5“L x 34”W x 30“H (diagonal of 49"). So we wouldn't have the capabilities in-house to chem film a cabinet that large. We can always look into third-party suppliers. Hope that helps!
Correct - we provide passivation for stainless steel only. For aluminum, if you require corrosion resistance, you could opt for chemical conversion coating or anodizing.

I have a requirement for "Clear Chromate Passivation" in Aluminium 5052 H32, Is this wrong as passivation is not for Aluminium?

Can u tell me how to make phosphating chemicals?
Hi there, our chem film treatment is supplied by one of our vendors, so we are unable to speak to the solution's makeup.
