摘　　要：全液压钻车摆臂结构件焊接完工后,孔的加工余量不均匀,孔加工不出来造成返修,费时费工,使孔壁外观厚薄不均匀,各个孔的中心距达不到图纸设计要求。针对多处尺寸出现偏差的问题分析发现,焊接过程中的焊接变形、各个单件尺寸的控制、组装结构件未使用工装是造成尺寸偏差的主要原因。为此,对上述问题提出改进措施,有效地控制了焊接品质,并使尺寸达到了图纸的设计要求。After welding the swing arm’ s structural member, the hole machining al owance can be uneven, the mochining holes can disappear and the central distance of every hole not meet the requirements of the layout design. By researching on the dimens and deviation in many places,it is found that the reason of the deviation is that fixture is not used in welding,control ing and assembling structural member. For this,the improvement measures are put forward to effectirely control the welding guality and make it meet the requirements.
