S195柴油机在使用过程中,由于连杆螺栓松脱,出现连杆将缸体上面捣洞的事故,如图1.近年来在推广铸铁零件加热减应焊的过程中,我们修复了一些这类缸体缺陷,情况良好.现将焊修过程简介如下. 一、焊前准备 1.将缸体需焊补部位清除铁锈、油垢及其它杂质.然后将破损部位边缘用錾子修圆(不能出现尖角,以免应力集中),并开出坡口. 2.按照破损部位修圆后的形状、大小,用3～5毫米的低碳钢板做成补板.为了与原工件形状一致,补板应做成搭接形状,如图2.
S195 diesel engine in use, due to loose connecting rod bolt, connecting rod will appear on the cylinder pounding accident, as shown in Figure 1. In recent years in the promotion of cast iron parts by heating the welding process, we have to repair some of these Cylinder body defects, in good condition. Now welding repair process is as follows .A pre-weld preparation 1 welding parts to be welded to remove rust, grease and other impurities.Then the edge of damaged parts prickly heat (can not appear Sharp corners, so as to avoid stress concentration), and out beveled. 2 according to the broken parts rounded after the shape, size, made of 3 to 5 mm low-carbon steel plate to make the plate. In order to be consistent with the original shape of the workpiece, Should be made lap shape, shown in Figure 2.
