中型挖掘机油管的焊接工艺设计摘要油管属于支架类零件，是减速器的包容件，对减速器的各零件起包容作用。它在减速器中是结构较复杂的零件。它不是传动件，受力不高。根据结构特点及使用性能选择 Q235-A 为盖板、轴承座及肋板等的材料。根据 Q235-A 钢选择合适的成型工艺以及焊接方法、编制合理的工艺规程、选择正确的装配方法、对焊接缺陷的预测、危害分析以及找出相关的补救措施。关键词：焊接工艺、焊接方法、焊接缺陷、焊接检验AbstractBox belongs to the bracket type parts, is the reducer of the inclusion of the parts of the reducer play an inclusive role. It is a complicated part in the reducer. It is not a transmission, the force is not high. According to the structural characteristics and performance, q235-a is selected as the material of cover plate, bearing seat and floor plate. According to q235-a steel select the appropriate molding process and welding method, prepare reasonable process procedures, select the correct assembly method, the prediction of welding defects, hazard analysis and find out the relevant remedial measures.Keywords: welding process, welding method, welding defects, welding inspection目 录摘要..........................................................................1引言..........................................................................2第一章 中型挖掘机油管焊接的母材选用及加工....................................31.1 母材的选用...........................................................31.2 钢材的矫正原理及方法.................................................31.3 划线..................................................................41.4 号料.................................................................41.4.1 号料的方法......................................................51.4.2 样板的分类......................................................51.4.3 号料的作用......................................................51.5 成形方法.......................
