What is Weld Cleaning?
Restoring Stainless Steel After Welding
What Happens When Stainless Steel Is Welded?
Stainless steel depends on a thin, chromium-rich passive oxide film for corrosion resistance. During welding, intense heat creates surface oxidation – the familiar straw, blue, purple, brown or black discoloration known as heat tint. The Welding Institute (TWI), an independent international research and technology organization, explains that a chromium-rich oxide scale forms while the surface immediately beneath it becomes chromium-depleted. If the affected surface is not properly treated, corrosion resistance can be reduced.
Why Clean Stainles Steel Welds?
A weld may be structurally sound while the surrounding stainless surface is no longer in optimum condition. Post-weld cleaning addresses oxide scale and contamination created during fabrication and prepares the stainless surface to regain its protective passive condition.
REMOVE HEAT TINT & OXIDATION
Removes visible oxide scale and weld discoloration.
RESTORE CORROSION RESISTANCE
Treats the heat-affected surface where corrosion performance can be reduced.
REMOVE FREE IRON & CONTAMINATION
Helps eliminate surface contaminants that can contribute to staining or corrosion.
PROMOTE A PASSIVE SURFACE
Leaves a clean stainless surface capable of forming its protective chromium-rich film.
PRESERVE THE WELD
Avoids unnecessary removal of the weld bead and surrounding base material.
IMPROVE APPEARANCE & SERVICE LIFE
Produces a professional finish while addressing the underlying surface condition.
A CLEAN-LOOKING WELD ISN'T JUST ABOUT APPEARANCE.
IT'S ABOUT RESTORING THE PERFORMANCE OF THE STAINLESS STEEL.
Technical basis: ASTM A380/A380M-25 and The Welding Institute (TWI) guidance on stainless-steel heat tint and post-weld cleaning.
Accelerate Your Post-Processing
One of the most costly and time-consuming shop processes is manual weld cleaning and passivation. Outdated and hazardous methods like pickling paste extend the time it takes to process products to completion.
Capital Weld Cleaner's electrochemical weld cleaning machines can double or even triple your post-processing speeds, saving you time, money, and sanity.

Industrial Welding Supply Inc.
Sam Flande (Distributor)
“IWSI has been very satisfied with the Capital Weld Cleaners. I have sold several of the 2×40 and a few 1×30 but just last month I sold a CW110 unit. Wow what a machine!!! I have a Freeze Dry plant in my area requiring the stainless to be cleaned and then cotton ball tested so no bacteria can hang up on any surface. This CW110 unit cleans & passivates the customers fabrications for this plant. They use these cleaners and are really pleased. We have good support from Capital Weld Cleaners.”
RPM INNOVATIONS, INC.
Jason Rhodes (Purchasing Mgr.)
“We have been using Pickling Paste for a number of years to clean our stainless steel boxes & we recently decided to give the 2X40 a try and wish we would’ve “tried” it much sooner. It cut our weld cleaning time by 90%! & paid for itself the first time we used it!”
AMERICAN INTERNATIONAL MFG. CO.
Sean D. (Production)
“I can up the amperage on the CW110 to Blast through the Weld Cleaning on our 5X4 Stainless Steel Hoppers much faster than anything else! I like using the Pump Gun the most. It gives me a continuous cleaning option that helps getting the job done quicker. The 2X40 unit has the Dual User option and both units have exponentially increased our efficiency.”
NEWFAB, INC.
Dan Komulainen
“We have owned the 2X40 weld cleaner for 2 years and love the quality and price.”
