目前我国对曲轴修复采用的工艺有:金属喷涂,气体保护振动焊,低温镀铁,等离子弧堆焊等等。就其工艺而论,各有利弊。总的来说,这些工艺都还不够完善,质量也不够稳定。埋弧堆焊又称焊剂下自动堆焊。目前我国许多农机修理单位已成功地用于修复磨损轮轴类另件,特别是用埋弧堆焊修复钢件曲轴,已取得了较好的经验。我省枣阳县农机修造厂,采用埋弧自动堆焊锻钢曲轴的时间比较长,积累了一定的经验。球墨铸铁曲轴广泛应用以 At present, China’s crankshaft repair process used are: metal spraying, gas protection vibration welding, low temperature iron plating, plasma arc surfacing and so on. In terms of its technology, each has its own advantages and disadvantages. In general, these processes are still not perfect, the quality is not stable enough. Submerged arc surfacing welding, also known as automatic welding. At present, many agricultural machinery repair units in our country have been successfully used to repair wear axles, especially the submerged arc surfacing repair of steel crankshaft, has gained good experience. Zaoyang County, Jiangsu Province, agricultural machinery repair shop, the use of submerged arc welding forged steel crankshaft for a long time, has accumulated some experience. Ductile iron crankshaft is widely used
