摘要
通过对空调与制冷用高频焊接内螺纹铜管焊缝微观组织特性的研究,找出了焊管质量问题的存在方式及其产生原因,提出了改进方法并加以实现,最终解决了生产中存在的问题,使产品质量得到了稳定。
The micro-character of weld line in copper tubes with inner grooved by high frequency welding for air-conditionings and refrigerators was briefly studied, the existent manner and the reason of quality problem were found out, betterment measure was put forward and realized, the problem in the production was settled and the product quality. became stable.
