摘　　要：对直缝焊管埋弧自动焊内焊多丝焊接规范设置进行了大量实验 ,通过对实验焊接规范分析 ,发现埋弧自动焊内焊多丝焊接规范设置存在一定规律 ,利用该规律能有效降低焊缝气孔、夹渣、烧穿等焊接缺陷产生。It takes a great deal of experiments for the setup of inside welding multiple wire welding specification in longitudinal submerged.It is found there is certain rule in setup of inside welding multiple wire welding specification in submerged arc automatic welding through the analysis of experiment welding specification.It can effectively reduce weld defect produced such as weld gas pore,slag inclusion and burn through,etc.by use this rule.
