THE MICROSTRUCTURE OF MANUAL ARGON ARC WELDING JOINT OF T91 STEEL TUBE
摘 要
对 60.3mm×8mm的T91钢管的母材及手工氩弧焊接头进行了化学成分、力学性能和显微组织的测定。结果表明,T91钢管的化学成分、力学性能和显微组织均满足GB 5310-1995的要求,焊接接头的组织为正常组织。
Abstract
The chemical composition analysis, mechanical properties testing and microstructure analysis of the base metal and manual argon arc welding joint of T91 steel tube with size of 60.3mm×8mm have been done in the paper. The results show that the chemical composition, mechanical properties and microstructure of T91 steel tube with size of 60.3mm×8mm meet the requirement of standard GB 5310-1995, and the microstructure of joint shows normal.
