研究了双面焊和单面焊双面成形2种不同接焊工艺，对工程机械用屈服强度为900 MPa级低合金、高强钢焊接接头力学性能的影响。结果表明，在相同的焊接线能量水平(≤15 kJ/cm)和 t8/5条件(≤20 s)下，采用双面焊工艺的焊接接头抗拉强度高于单面焊双面成形。

Influence of different process that is welded by both side and welded by one side on mechanical behavior of butt welding joint of 900 MPa yield-strength low-ally steel was studied.According to the results of verification test,the ten-sile strength of both side welding joint was higher than that of one side welding joint in the same heat input (within 15 kJ/cm)and t8/5 time (within 20 s).
