伴随着我国人民生活水平的提高,电冰箱等制冷设备的应用越来越广泛。为了节约用铜,绝大多数类型的电冰箱均采用铝制蒸发器,其外部则采用铜材管路,为此需要解决铝—铜薄壁管的焊接问题。冶金部建筑研究总院与北京顺义制冷设备配件厂采用摩擦焊的方法,解决了铝一铜薄壁管(φ8×1)的焊接技术,其铝—铜薄壁管过渡段摩擦焊接新产品也通过了技术鉴定。鉴定会的代表检查了用该方
With the improvement of people’s living standards in our country, the application of refrigeration equipment such as refrigerators is becoming more and more widespread. In order to save on copper, most types of refrigerators use aluminum evaporators and copper pipes on the outside. Therefore, it is necessary to solve the welding problem of aluminum-copper thin-walled tubes. Ministry of Metallurgical Building Research Institute and Beijing Shunyi Refrigeration Equipment Parts Factory using friction welding method to solve the aluminum-copper thin-walled tube (φ8 × 1) of the welding technology, the aluminum-copper thin-walled tube transition welding friction products also Passed the technical appraisal Representatives of the appraisal committee checked the party
