| Abstract: | HP40 oven pipe is one of the centrifugal cast pipe of thermal resistant austenitic stainless steel.The component of this alloy is complicated and it is hard to be welded. During welding it is easy tocause heat crack in melt zone and over heat zone. By choosing foreign material which basing materialcomponent is close to HP40 and by selecting appropriate welding process parameter and technologymeasure, it acquires high quality welding joint. |
