直边对接悬空双面埋弧焊在实际生产中的应用

Application of straight edge butt double-sided submerged arc welding in actual production

由于大型起重机跨度及主梁腹板宽度都比较大,主梁腹板拼接制作过程中,采用直边对接悬空双面埋弧焊在保证焊接质量的前提下,能极大地提高焊接生产率,可以节省时间、人力及焊接材料。δ=12～18mm直边对接悬空双面埋弧焊在实际生产中具有实用价值。

Due to large span of huge crane and wide girder web,during splicing and manufacturing of the girder web,the straight edge butt double-sided submerged arc welding are used to greatly improve the welding productivity,and save time,labor and welding materials under the premise of ensuring welding quality.The straight edge butt double-sided submerged arc welding with straight edges from δ=12 mm to δ=18 mm has practical value in the actual production.
