摘要
Abstract
Based on the analysis of the curre ntly-used welding technologies,a technological scheme of hot-cold double-wire SAW for the heavy-wall steel pipe is proposed here in the paper.Specifically the said scheme covers such a operation mode,i.e.,getting two welding wires with different thermal states simultaneously enter the SAW process by me-ans of setting a metallurgical reaction molten pool so as to achieve both stable quality control and rapid enhancement of the productivity of the DH36-Z35 heavy-wall welded pipe.Relevant industrial experiment result shows that thanks to the above mentioned cold-hot double-wire SAW process,proper control of the low hot output and high metal deposition eff-iciency of the heavy-wall steel tube welding process are obtained,which is of reference value for enhancing the productivity of the heavy-wall(t≥50 mm)DH36-Z35 welded steel pipe.关键词
