If you get a "natural effervescence" welding then you can try it.
this for welding of oxyethylene, and electrical wire or electrode
someone manages to get results just a little more decent with the tig, but we are still far from welds worthy of that name, also because the transition zone base metal/welding remains always very fragile.
Thank you 1000!
then I did not wrong to tell my boss that they are not weldable (you know, the tig costs too much!!!) and that, given the application, it was better to do everything in fe.
