摘　　要：2015年12月16日由上海发那科机器人有限公司FANUC、广州阿比泰克焊接技术有限公司BINZEL、普莱克斯（中国）投资有限公司PRAXAIR、捷锐企业（上海）有限公司GENTEC共同举办的＂2015年华东区焊接技术交流会＂在上海发那科机器人有限公司工业园区举行,大会的主题为：＂集工业工程专家之智慧,益产品创新与发展＂,Based on software SYSWELD,the stress field and the welding microstructure in T-junction of Q345D using TIG welding technology are simulated.The stress of welding bead is tensile stress,the stress of HAZ is compressive stress,the stress of the wing plate＇s sides is tensile stress.Further simulation to be done,it is found that there are lots of martensites in HAZ.Besides,the correctness of numerical simulation is verified by experiments. It can be concluded that the reason of compressive stress in HAZ is the occurrence of martensitic transformation. Volume expansion of HAZ is caused by martensite lead to compressive stress which is greater than tensile stress caused by cooling contraction.
