Welding Inconel UNS 6625 to Low temp Carbon Steel (A333 Gr6)
(OP)
Hi Friends,
We qualified PQR inconel UNS 6625 weld to low temp Carbon Steel (A333 Gr 6). All mechanicate passed except Root bend test. The defect lack of fusion at boundary have appeared manny time. We try many time but still similar defect.
Would like give some information for your study:
Welding Consumable: Tech-Rod 112, ER NiCrMo-3 Techlloy
Heat input: 1.2-1.8 (Kj/mm)
Type bend: Root Bend
Jig Bend: 40 mm (4xt)
The picture for your refer

Inconel is notorious for being hard to weld or use as a filler. Hire the best welder you can find. It'll be much less expensive than all the rejects/repairs you have been having. A top-notch welder can make that weld. But not an average one.
Cheap welders can be incredibly expensive. Expensive, excellent welders can end up being cheaper than run-of-the mill welders.
