摘要
用添加合金粉末埋弧焊工艺可以大线能量焊接16MnR钢,单道焊缝的熔深可达20mm,焊接熔敷速度大于26.6kg/h,熔敷系数大于34.6g/h·A,焊缝和HAZ的显微组织良好,焊接接头常温力学性能达到国家标准要求。
HSLA steel 16MnR is welded by SAW with alloyed metal powder and the maximum penetration of 20 mm for single pass can be obtained. The deposi on rate of the process is more than 26.6 kg/h and the deposition coefficient is more than 34.6 g/h ?A·The microstructures of weld metal and HAZ are fine and the mechanical properties of welded joint are identical with that by ordinary SAW process.
