我所受岳阳石化总厂之委托,将基础研究成果——插销试验法及其他理论,结合对15MnVR压力容器用钢焊接性的研究,应用到岳化总厂三台1000米~3球罐的补焊试验研究及返修工作中,在生产上得到了实际应用,创造了较大的经济效益。我所对这三台待修球罐作了一系列的试验研究工作,如通过断口及接头的金相、扫描电镜、电子探计分析,研究了裂纹性质与成因,用插销试验法及焊缝性能对比试验选定了补焊用焊条以及不同的焊后消除应力热处理温度对
I was commissioned by Yueyang Petrochemical Plant, the basic research results - plug test method and other theories, combined with 15MnVR pressure vessel steel weldability applied to the three plants in Yuehua Plant 1000-3 ball tank Welding repair test and repair work, in production has been the practical application, and create greater economic benefits. I conducted a series of experimental studies on the three tanks to be repaired, such as the fracture and joint metallography, scanning electron microscopy, electronic exploration analysis, the study of the nature and causes of cracks, with the pin test and weld Performance comparison test selected welding electrodes and welding different after stress relief heat treatment temperature
