We performed welding on a tube sheet of our urea stripper having following material:
CLADDING (10 MM THICK) = ASME SB 265 GR-2
TUBES = ASME SB-338 GR-3
Cracks are observed after welding, my question is:
Is this possible that commercially pure titanium of above grades transforms into martensitic structure? if yes then under what conditions?
