摘　　要：为了提高直缝埋弧焊管多丝埋弧焊接速度,采用预热四丝埋弧焊接工艺进行了X60钢级Ф559 mm×32 mm规格钢管焊接对比试验,并与常规四丝埋弧焊工艺进行对比。对比试验发现,与常规四丝埋弧焊工艺相比,采用预热四丝埋弧焊工艺时,可提高焊接速度20%,降低焊接线能量10%,整体力学性能优。证明预热多丝埋弧焊工艺在保证焊缝质量、力学性能的前提下,可以显著提高直缝埋弧焊管的焊接速度,是一种优质、高效、节能的埋弧焊新工艺。In order to increase the multi-wire SAW welding speed for the LSAW pipe,the welding comparative experiment for the X60Ф559 mm×32 mm steel pipe is conducted via the pre-heating 4-wire SAW process,and a comparison with the conventional 4-wire SAW process is made.The result shows that compared with the said conventional 4-wire SAW process,the pre-heating 4-wire SAW process brings about such advantages as the welding speed is increased by 20%,the welding wire energy consumption is reduced by 10%,and the overall mechanical performance is excellent.It is proved that under the pre-conditions that the weld quality and the mechanical properties of the pipe are guaranteed,the above mentioned pre-heating multi-wire SAW process can obviously increase the welding speed for the LSAW pipe.
