摘要
Abstract
In order to increase the multi-wire SAW welding speed for the LSAW pipe,the welding comparative ex-periment for the X60 Φ559 mm×32 mm steel pipe is conducted via the pre-heating 4-wire SAW process,and a compa-rison 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.关键词
