药芯焊丝由于具有生产效率高,焊接质量好,综合焊接成本低等优点而成为世界焊材发展的新趋势,所以国内最近十年共有十几家先后引进20多条生产线,耗资近2亿人民币,然而大多都失败了,只有一条正常运转,主要是核心技术还不能全面转让,被国外少数跨国公司垄断。而天津三英焊业公司的异军突起,打破了国外的垄断,坚持自主研究、开发适合中国资源特点的焊丝成套生
Due to its advantages of high production efficiency, good welding quality and low total cost of welding, the flux-cored wire has become a new trend in the development of welding consumables in the world. Therefore, more than a dozen domestic manufacturers have successively introduced more than 20 production lines at a cost of nearly 200 million RMB However, most of them failed. Only one of them is normal. The main reason is that the core technology can not be fully transferred and is monopolized by a few foreign multinational corporations. The sudden emergence of Tianjin Sanying Welding Co., broke the monopoly of foreign countries, insisted on independent research and development of welding wire complete sets suitable for the characteristics of China's resources
