摘要
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(≤15kJ/cm)和t8/5条件(≤20s)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 tensile strength of both side welding joint was higher than that of one side welding joint in the same heat input（within 15kJ/cm）and t8/5time（within 20s）.
