According to the information in the world in steel production by about 50% of the welding process from raw material into finished products. At present, many welding operations have been mechanized, automated, NC, artificial intelligence, and many other high-tech. According to the information to incomplete statistics, in some industrialized countries has reached the average level of mechanization of welding 70% to 80%, while only 20% of 30%, most of the welding operation can not be separated manually.

With the development of production and scientific and technological progress, welding has become - an independent discipline, and is widely used in aerospace, aviation, nuclear industry, shipbuilding, construction and machinery and other industrial sectors in China's national economic development, particularly is the manufacturing industry, the welding technology is an indispensable means of processing. To natural gas projects, for example, total length of 4,300 km of gas pipeline, the number of welded joints as high as 350,000 or more, the length of the pipe weld at least 10 005 thousand kilometers. National Theatre for a share of the 6700 tons of steel, weld up to 100 km, if not already good prefabricated welded to weld together the scene also has 35 km long and need more than 100 excellent welding electrodes, consuming 87 tons electrode. Beijing Olympic Bird's Nest 11 million tons of steel used, the weld 320 km long, 20,100 tons used in the electrode can be a full three times around the Earth's equator. Out welding, can not imagine how to complete this project.

Welding Rods" professional development in foreign countries is to improve the degree of specialization, and the increasingly easy operation, automation, integration, welding technology is highly developed with foreign corresponding. Widespread use of automatic welding equipment abroad, and its degree of automation and control of high precision, weld quality and stability. This requires welders not only to master the basics of welding and professional skills, but also to the use and operation of various types of advanced, precision welding equipment and control instrumentation. Therefore, long-time welders often systematic and comprehensive training, education, can perform the work of welding jobs.

The intricate "welder complex." Natural gas project to a salary of 150 yuan per day posting recruiting senior welder. A private bosses lamented: "the recruitment of senior welder 8,000 yuan monthly salary!" Kunshan City, Jiangsu Province, and even some companies bid 28 million annual salary of employed senior welder.

Welding Association recently found that a city in the automotive, boiler, shipbuilding and other manufacturing industries, the general lack of professional welder or can not meet existing quality welders production development and technical innovation of the new requirements, some of which have seriously affected the development of new products, product quality and production tasks. Some provinces and cities, according to the labor department of the investigation and analysis of market forecasts and reflect the talent exchange of information show that the demand for skilled personnel and recruitment, especially senior welder welding over gaps in talent is one of the largest trades.

Into the twenty-first century, as a manufacturing welding is an important part in a rapid development, which to our welding industry with unprecedented opportunities for development, but also for the majority of welders provide professional practitioners to display their talent stage and opportunities.
