The distinguishing features of welding and control method of welding deformation for welding of H section steel are introduced. The welding condition of automatic submerged arc welding with flux backing is determined by the test of welding technology. 介绍了H型钢的焊接特点及焊接变形的控制方法,并通过焊接工艺试验确定了带焊剂垫埋弧自动焊的焊接工艺参数。
There are a lot of inclusions in weld bead by CO2 arc shielded welding using flux cored wire and ceramic backing. 药芯焊丝陶质衬垫CO2半自动单面焊焊缝中的夹杂物偏多。
Welding efficiency is raised greatly by using submerged arc welding technology and erecting reliable flux backing simply. 采用带焊剂垫埋弧自动焊工艺可大大提高H型钢的焊接工作效率。
In order to improve the welding productive and short the period efficiency of ship-building, the high efficient welding technique has been used in many domestic shipyards. FCB is short for the high efficient technique of flux and copper backing with one-side welding both-side forming. 为了提高造船的生产效率,缩短造船周期,国内许多大型造船厂采用焊剂铜衬垫单面焊双面成形的高效焊接方法,简称FCB法。
