By doing pickling and passivation of Stainless Steel weld joints with novel gel / jelly type product it removes weld scales, discolouration, burn marks, rust - corrosion spots from weld seam & surrounding areas without wire brushing or grinding. If that are not cleaned then corrosion can develop in that area.

There are many novel surface treatments for Stainless Steel pickling & passivation which conform to International standards and gives professional looking passive surface finish.
