Hi
I understand this group is more about Fusion welding, but I have a problem with Spot welding which I hope someone can help.
I have been looking for a pre Mixed solution to Etch Stainless Steel Spot welded coupons to check the Nugget characteristics. I know its a mixture of Sulfuric and Nitric Acids+ another very nasty Acid, and I hate to be the one mixing them.
I am sure there has to be someone selling this solution premixed, ready to use.
Thanks for your help.
