Analysis on the Cause of Leak in Welding Line in Steam Tube and Its Improvement

SHAN Hong-wei~1,XIE Ying~2(1.Center of Industrial Technology,Chengde Petroleum College,Chengde, Hebei 067000,China2.Department of Mechanical Engineering,Chengde Petroleum College,Chengde,Hebei 067000,China)  
The reason why leak occurs in the welding line of steam tube is analyzed,the crack is considered as the result of wrong welding techniques or operation.The paper analyzes the cause of its formation and proposes the countermeasures accordingly.
