How to transfer from argon arc welding to submerged arc welding when the inner cylinder of16mdr head is welded with the inner cylinder of18ni9?
The base material of the container in our factory is 16MNDR, and the girth weld between the head and the cylinder is automatic argon arc welding+submerged arc welding! The original process is: manual argon arc welding+manual arc welding+submerged arc welding. A bushing is added between the head and the barrel joint. The lining material is 16MNDR with a thickness of 6MM. The welding effect is good, it has been done for more than ten years and thousands of sets, and there is no quality problem. I hope I can help you!
