摘要
20g材料在进行埋弧自动焊接时易出现冷弯开裂;且中厚板的埋弧自动焊接不易清渣。采用台阶型坡口很好地解决了塔设备制造中存在的这些问题。通过焊接工艺试验,确定了焊缝的坡口尺寸、焊接工艺和施焊程序。
When welded in way of auto-submerged arc welding, steel 20g is easy to cause cold bending and cracking. ln addition, it isn＇t easy to clean the welded redundant. These problems in manufacture of tower equipment can be well solved by using stairstep welding groove. By welding condition test, the size of groove, welding parameters and welding procedure can be determined.
