How should the weld seam be treated after stainless steel welding? Pickling?
Pickling with pickling paste gives the weld seam a shiny finish.
Austenitic stainless steel welds generally only require pickling and passivation; welding of ferritic and martensitic steels may require heat treatment, depending on the electrodes chosen and the welding process used.
For non-special applications, post-weld treatment can be carried out immediately while the metal is still hot, using a pneumatic polishing disc. The results will be very good.
It can be mechanically polished or pickled with an acidizing paste
After welding, should non-destructive testing be carried out first or some other treatment? If there are issues detected during non-destructive testing, would carrying out other treatments be a waste of effort? ?
