Analysis on Welding Mechanical Performance of S460M Steel Plate

对S460M钢板进行了焊条电弧焊与埋弧焊试验,从试验结果看,S460M钢板在热输入为15～18 kJ/cm的焊条电弧焊与热输入为13～40 kJ/cm的埋弧焊条件下焊接,焊接接头的拉伸性能、弯曲性能和冲击性能良好。试验结果表明,该材料的焊接接头性能优良。

In order to analyze the welding mechanics properties of S460M steel plate, S460M steel plate was welded by the rod arc welding and the submerged-arc welding experiment. From the test results, the welded joint stretch performance, the curving performance and the impact performance are good, when S460M steel plate was welded by the rod arc welding under the welding heat input of 15-18kJ/cm and the submerged-arc welding heat input of 13-40kJ/cm. The results show that the arc welded joint performance of the S460M steel plate is good.
