为提高钢材拼焊效率,由成都电焊机研究所设计,广东揭阳电焊机厂制造了一台 MZ-2000型双丝埋弧焊机,并在自贡东方锅炉厂对25毫米厚的16Mn 钢板单面焊双面成形工艺进行了一系列实验,获得成形较好,机械性能和金相组织符合要求的焊缝。
In order to improve the efficiency of steel welding, designed by Chengdu Electric Welding Machine Research Institute, Guangdong Jieyang Electric Welding Machine Factory made a MZ-2000 double-wire submerged arc welding machine, and in Zigong Dongfang Boiler Factory 25mm thick 16Mn steel single-sided Welding double-sided forming process conducted a series of experiments, get better forming, mechanical properties and microstructure meet the requirements of the weld.
