1962年我厂组织了三结合的电振动堆焊研究小组,开始对电振动堆焊进行试验研究,并在1964年正式用于生产。后来又通过各项试验研究,反复实践,终于采用水蒸气保护的电振动堆焊工艺,解决了修复汽车曲轴的质量问题。至目前为止,已堆焊汽车曲轴近3000根,最长行驶里程达30多万公里,实践表明堆焊曲轴性能良好,报废率在5%以下。一、堆焊试验曲轴是发动机上的重要部件,它在使用中要承受较大的交变载荷或冲击载荷,因此它对堆焊的质量要求较高。但振动堆焊的焊层易产生气孔和裂纹,因而
In 1962, our factory organized a three-in-one research group of electric vibration welding and surfacing, started the experimental research on electric vibration welding and was formally used for production in 1964. Later, through various experimental studies, repeated practice, and finally using water vapor to protect the electric vibration welding process, to solve the quality problem of repairing the automobile crankshaft. So far, the car has been surfacing nearly 3000 crankshaft, the longest driving range of more than 30 million km, practice shows that the performance of a good crankshaft surfacing, scrapped less than 5%. First, surfacing test Crankshaft is an important part of the engine, which in use to withstand greater alternating load or impact load, so it requires a higher quality surfacing. However, vibration welding surfacing easy to produce pores and cracks, and therefore
