Tips for removing the color from welded stainless steel
Anyone have any good tips for removing the oxidation color from stainless steel after you have welded on it?
We had a project that had some A304 SS window lintels added to our contract. These 3/8" thick plates were 30.5" wide x 30' long and were stitch welded with intermittant fillet welds to the main structural steel above. The heat from welding had oxidized on bottom (opposite) side of these plates and the Architech on the job asked us to address this.
A trip to the grocery store proved to be fairly beneficial. I found 100% lemon juice(citric acid) seemed to get the job done and is enviromentally friendly and not hazardous to your health when using it.
samples as welded...
samples cleaned, one with lemon juice and one with CLR

Hey that's good info... wonder if it would work on header blue? Probably not, but it would be cool if it did.

There is something that will get that off....(BTW, correct shielding coverage will prevent it in the first place)
