摘要
通过对 T91钢薄壁管不预热、不热处理进行焊接的试验和检验 ,考查 T91钢薄壁管焊接的裂纹倾向 ,探讨通过工艺措施解决焊态接头硬度过高及改善接头韧性的方法。通过模拟工况试验 ,探讨工况温度和压力对
Through the experiment of welding process on T91 thin steel pipe without preheat and post weld heat treatment,the crazing tendency of welded pipe was investigated and the technique to improve the toughness of the joint was studied.By means of test under imitative condition,the influence of temperature and pressure on the welded joint was discussed.
