There is a case about welding titanium cladded carbon steel(516 Gr 70)
to stainless steel (316 Ti) and i need some advice. What problems can
occur during the welding, which precautions should i take, also is GTAW
the best process for this joint? And what kind of filler material
should i choose. I'll be very gladfull if you can help me.
In my opinion you must eliminate theTitanium for 2-3 cm therefore to
put to knot the steel, weld the steel and the 316 with the 309SS then
to bring back titanium (TIG recladding) in order to cover the welding
zone. TIG is the best proces.
The recladding of Titanium must be under inert gas ( Argon ) with one
large ceramic cup.
