随着造船工业的不断发展,黄铜的消毫量越来越大。为了节约有色金属,几年来,对气体熔剂堆焊黄铜的工艺进行了反复的摸索和试验,攻克了技术关和设备关,提高了产品质量,扩大了该工艺的应用范围。黄铜焊接目前仍以气焊为主。用氧—乙炔火焰、并加硼酸和硼砂作为熔剂而进行焊接的方法比较成熟,但存在不少缺点。采用气体熔剂堆焊黄铜,是近十多年发 With the continuous development of the shipbuilding industry, the consumption of brass is getting bigger and bigger. In order to save non-ferrous metals, over the past few years, the process of welding gas flux brazing repeated exploration and test to overcome the technical and equipment off, improve product quality and expand the scope of application of the process. Brazing welding is still the main gas welding. With oxygen - acetylene flame, and add boric acid and borax as a flux for welding method is relatively mature, but there are many shortcomings. The use of gas flux welding brass, is nearly ten years of hair
