| Abstract: | In the 200×104t/a diesel oil hydrogenation facility in Guangxi Petrochemical Co.,there are 8 mm thick Inconel625 layers formed by surfacing welding around the holes of some high pressure heat exchanger,where TP347 steel pipes are needed to connected. Therefore,the weldability between the dissimilar steels of Inconel625 and TP347 is analyzed,then proper welding process is formulated,and strict welding process assessment tests and field quality control are carried out. Finally,the welding task is fulfilled satisfactorily. |
