摘　　要：热交换器中换热管与管板的焊接质量直接影响整个换热器的使用寿命,由于此设备采用内孔焊的焊接方式,管板与换热管的对接坡口加工质量十分关键。本文针该坡口的加工进行研究和改进,采用非标刀具的方式,在保证加工质量的同时,大幅度提高了加工效率。The welding quality of heat exchanger tube and tube plate in heat exchanger has a direct impact on the service life of the heat exchanger. The welding quality of the tube plate and the heat exchanger tube is very important because of the inner Kong Han welding method. In this paper, the machining of the groove is studied and improved, and the machining efficiency is improved greatly by using the non-standard cutting tool.
