随着我国经济的发展,不锈钢制品的用量越来越大,不锈钢焊条的使用量也越来越大。据保守估计,1998年我国不锈钢焊条的产销量已达到8000t以上。目前我国不锈钢焊条的性能较以往已有了较大的提高,但与国外名牌产品相比,仍有较大差距。例如,施焊时飞溅大,焊缝成形不美观,气孔敏感性有时较大,在正常施焊电流下焊条药皮易发红脱落等。另外,由于熔敷金属含碳量较高,与国外名牌焊条相比,耐腐蚀性能也存在较大差距。 针对国产不锈钢焊条存在的问题,我们进行了大量的研究与探索,成功地开发出适合中国国情的金威牌优质不锈钢焊条。
With the development of our economy, the amount of stainless steel products is increasing, the use of stainless steel electrodes is also growing. According to conservative estimates, in 1998 the production and sales of stainless steel electrode in China has reached more than 8000t. At present, the performance of stainless steel electrode in our country has been greatly improved compared with the past, but compared with foreign brand-name products, there is still a big gap. For example, when the welding spatter, weld appearance is not beautiful, stomatal sensitivity is sometimes larger, in the normal welding current welding electrode dandruff easily fall off. In addition, due to the higher carbon content of deposited metal, compared with foreign brand-name electrode, there is a big gap between the corrosion resistance. For domestic stainless steel electrode problems, we conducted a lot of research and exploration, successfully developed for the Chinese national conditions Jinwei brand high-quality stainless steel electrode.
