I'm working as  a TPI with a vessel manufacturing ,last week during inspection we found a 2'' nozzle 3 feet long Sa333 Gr6  which shall be SS316 weld overlay with single joint but due to the small diameter  this nozzle divided to a three part and after cladding manufacture made butt weld joints by a Ni ,Mo electrode GTAW ,is that the perfect solution ?what will be the alternative ?
