摘要
Abstract
The weldability of T91/P91 steel was analyzed, the selection principle of the steel welding consumables was discussed and the types and applications of the steel welding consumables were introduced.The results show that the welding consumable selection of T91/P91 steel can use "quasi-element matching" principle .that is to make the main chemical composition of the weld metal close to base metal as far as possible, and to guarantee the welded joint obtaining the best mechanical properties (including high temperature properties) and weldability.There are five kinds of welding consumables used in T91/P91 steel,the new welding technology of backing welding by FCAW plus filling welding by GMAW has obvious advantages.The applications of matching welding consumables and appropriate welding technology in pipeline welding are successful.The special flux cored wire for T91/P91 steel is a new welding consumable with development prospect and need improvement.关键词
