我车间三结合焊接技术攻关小组,为进一步提高自动焊焊接效率,减少刨边,挖焊根,除渣等辅助工时;节约焊丝、熔剂等原材料。对14～24毫米常用厚度钢板的平直焊缝,进行不开坡口的双面单道自动焊接工艺试验,用“优选法”选择焊接规范。经过试验,在接头焊透程度,机械性能,外观和X光透视等指标中,都取得较好结果,并已部份应用到生产上。现介绍如下: I workshop three welding technology research group, in order to further improve the efficiency of automatic welding, cutting edges, digging root, slag and other auxiliary working hours; saving wire, flux and other raw materials. The flat welds of 14 to 24 mm thick steel plates were subjected to a double-sided single-pass automatic welding process without a groove, and the welding method was selected by the “preferred method”. After testing, in the joints penetration, mechanical properties, appearance and X-ray and other indicators, have achieved good results, and has been partially applied to the production. Now introduced as follows:
