钨极在焊接中的应用很广泛,由于焊枪结构的原因,每根钨极有1/3不能继续使用。钨极是由钨、钍钨等稀有金属制成的,价格很贵。象我厂的生产规模,每年至少要用10kg,按1/3计算每年要浪费3kg以上,合人民币1200元左右。为此,我们决定把废钨极焊接起来继续使用,其工艺如下。 Tungsten in the welding of a wide range of applications, due to the structure of the torch, each tungsten 1/3 can not continue to use. Tungsten is made of tungsten, thorium tungsten and other rare metals, the price is very expensive. As I plant the scale of production, at least 10kg per year, according to 1/3 of the annual waste of 3kg or more, together with about 1,200 yuan. To this end, we have decided to waste tungsten welding continue to use, the process is as follows.
