| Abstract: | This paper makes research on the causes early failure of dissimilar steel pipe welding of overheater. It shows that the objection in parent material and welding joins is main reasons causing failure of overheater. Therefore, it is necessary to enhance the quality of raw material and improve the welding process conditions so as to overcome the early failure. |
