摘要
通过室温拉伸和硬度及分析等方式,对Q450NQR1耐候钢混合气体保护焊焊接接头的力学性能进行了研究,试验结果表明:CHW-55CNH实芯焊丝焊接时,可以获得拉伸性能均良好的焊接接头,焊缝区硬度较均匀,焊缝的硬度在170～220 HV之间。
Through room temperature tensile and hardness and metallographie analysis of Q450NQR1 weathering steel mixed gas arc welding the mechanical properties of welded joints and microstrueture were studied. The results show that： with CHW-55CNH solid wire welding, you can be stretching properties of welded joints are good; more uniform hardness of the weld zone, weld between the hardness of 170 - 220 HV.
