犁铧手工电弧焊焊条及工艺研究是一机部基础件攻关项目之一,最近通过了鉴定。鉴定会议认为:1.硼铸铁焊条(JHB)堆焊新犁铧的使用寿命比65SiMn 钢淬火犁铧提高1～2倍,一片堆焊犁铧能顶2～3片新犁铧使用,达到了部下达的攻关指标。采用这种焊条堆焊修复旧的犁铧也能顶1.5～2片新犁铧使用,效果显著。2.堆焊工艺采用冷焊法,简便易行,便于推广。可以做为农村公社、农牧场、拖拉机站等部门,对犁铧以及其它某些易磨损零件如松土铲、犁臂、犁侧板、 Plowshare manual arc welding electrode and the process of research is one of the basic unit of the research project, recently passed the appraisal. Identification of the meeting that: 1. Boron cast iron welding rod (JHB) surfacing new plowshare life than 65SiMn steel hardened plowshares increased by 1 to 2 times, a plow plowshare to the top of 2 to 3 pieces of new plowshare, reached the ministry attack index. The use of such electrode surfacing repair old plowshare can also top 1.5 to 2 new plowshare use, the effect is significant. 2. Surfacing process using cold welding method, simple, easy to promote. Can be used as rural communes, farms, tractor stations and other departments on the ploughshare and other parts of some easy to wear such as earth shovel, plow arm, plow side panels,
