传统的通行的高速钢刀片的焊接方法是钎焊,钎焊剂需用宝贵的铜,又要经过熔炼和加工成碎屑等复杂工艺。近来,我们研究采用一种新的焊剂,这种焊剂价格只有铜合金的千分之几的活性碳。这种焊接方法容易掌握,设备简单,焊剂便宜,并且碳极易粉碎。所以这种新技术有利于普遍推广。 Conventional high-speed steel blade welding method is brazing, brazing flux need to use precious copper, but also through melting and processing into debris and other complex processes. Recently, we have studied the use of a new type of flux, which is only a few thousandths of that of copper alloys. This kind of welding method is easy to grasp, the equipment is simple, the flux is cheap, and the carbon is easily crushed. So this new technology is conducive to universal promotion.
