Cleaning Stainless Welds


Cleaning stainless after welding: We are Mig welding stainless steel and are having problems cleaning the parts that overheat during the welding process. The are blue from overheating and also have a flux type residue on the weld. They are mass produced parts and our pickler is having difficulty with cleaning them. Any suggestions?

G'day Mate! Neville you some serious attention to detail in the shop to improve the MIG weld process first. MIG by its nature tends to generate a huge amount of turbulence in the IG stream. This leads to some pretty foxy oxides that the pickling guys hate. However, with some attention to detail you can improve the weld quality, reduce the finishing cost. The best bit is it takes no longer and you get a better result! Cheers

We need information about this for racking material. What can we use to passivate type 303 stainless steel racks?

Thank You,

Hi, Claudia

Either citric acid or nitric acid can be used to passivate 303 stainless steel. Please search our site for "passivate stainless steel" for some good discussions.
