Plasma surfacing technology is a method of strengthening and repairing the surface substrate. The performance of the surface of the parent material has been worn out or the worn parts are restored to their original dimensions. How is plasma surfacing technology developed so that plasma surfacing technology is so strong?
The basic methods of surfacing welding technology in China in the 1950s were electroslag surfacing, submerged arc welding, arc welding (electrode) and so on. Although it is widely used in some machinery industries, it has not formed an industry. In the 1960s, China established the Welding Society of China Mechanical Engineering Society, and learned to conduct academic seminars on the current industry, which greatly promoted the progress of China's surfacing industry and was in line with the international surfacing profession. It plays a vital role in the surfacing business in China and the cultivation of surfacing talents.
Compared with other industries, surfacing is also a relatively traditional technology in China. However, compared with the development of technology, the surfacing requirements of various products are getting higher and higher, and the precision of products is becoming more and more accurate. Ordinary surfacing technology has been difficult to meet the surfacing requirements of current products. The product manufacturing industry, the mechanical processing industry, the coal mining industry, etc. - the series of industries are also increasingly dependent on surfacing technology. The awareness of energy conservation and environmental protection advocated by the state is getting stronger and stronger. Surfacing technology ushered in the second spring. The advancement of science and technology has also promoted the development of surfacing, and the surfacing business in China has also been continuously developed in various surfacing industries.
Plasma surfacing technology is also the most important. Represented by plasma arc surfacing in the 1970s, various welding institutes in China have also introduced various types of plasma arc surfacing machines, and actively cooperated with large surfacing giants. The experimental results are also perfect. Plasma surfacing technology has also been greatly promoted by various industries.
In the 1980s, domestic surfacing researchers studied actively in foreign countries. Solved the problem of excessive surfacing cost. The service life has been increased by a factor of two. In the medium term, the original Fe-5 wear-resistant alloy was replaced with Co-based stellite No. 6 gold, and the price dropped by about half compared with the previous one.
In the 1990s, as the scale of our domestic metallurgical industry expanded, so did the demand for surfacing. The new research of China Research Institute has also been put into use in all major industries in China. The yield rate is 40%. Effectively promote the development of China's wear-resistant technology. Entering the 20th century, the strategic implementation, infrastructure construction and mechanical processing of China's Belt and Road Initiative are not only in China. Large-scale construction, machining. It is bound to increase the degree of mechanical wear and the plasma surfacing technology will be more widely used.
Under the leadership of the older generation of researchers, China has also become a research power in plasma surfacing technology. Become the benchmark in this field. Plasma surfacing technology will also lead the world under the leadership of a new generation of surfacing personnel.
