摘　　要：为了免除背面清根,预防根部裂纹,对组焊H形钢T形接头埋弧焊工艺进行了分析和焊接试验。结果表明,在合理设计接头坡口角度、钝边尺寸和焊接规范等参数的情况下,可免除接头背面清根,且避免焊缝根部裂纹的产生。Based on the welding experiments,welding process of T joint of H shaped steel was analyzed to avoid back gouging and prevent the root cracking.The results show that no back gouging and prevention of the root cracking can be realized by the rational design of groove angle, thickness of root face and welding parameters.
