摘要
进行了N80L钢制作高强度焊接井架立柱的工艺试验,选定了合理的煨弯和手工电弧焊工艺参数,并生产了井架两套,使用效果良好.
Experimental study is carried out for procedure parameters in order to weld columns of pit frames made from N80L high strength steel. The reasonable parameters of slow bending and manual welding arc selected. 24 elbows and 660 weld joints for two sets of pit frames fabricated with the procedure are totally acceptable and after 3 years service it is found that the columns of pit frame well fulfills the design requirement.
