I AM LOOKING FOR AN ALTERNATIVE TO CHEMICAL ETCH FOR CLEANING
PARTS BEFORE SPOTWELD. WE CURRENTLY SPOTWELD ALUMINUM, TITANIUM, AND STAINLESS STEELS FOR AEROSPACE STRUCTURES.WE ARE SEEKING ALTERNATE METHODS DUE TO ENVIORNMENTAL ISSSUES.
I REALIZE THAT SPECS DRIVE THE CHEMICAL ETCH BUT I WOULD REQUEST SPEC CHANGES IF THERE IS AN ALTERNATE PROCESS
