In addition to conventional arc welding, gas shielded arc welding, submerged arc welding, plasma arc welding, electroslag welding, friction welding and other technology is widely used, some new welding technology has been applied in various fields in China's manufacturing industry.
Friction stir welding invented by British Welding Institute is a new solid-state welding technology, in aviation, aerospace and shipbuilding sector has used this technology for aluminum welding, achieved very good results. China has also introduced this patented technology, but it has a lot of research and development space.
There are a variety of welding technology. Vacuum brazing applied to limousine aluminum plate cooler welding, aluminum cooler are more suitable for high-volume automotive industry, high-efficiency, low-cost, long-life. Surface flame welding technology applied to heavy mining industry walled roller conveyor, successfully completed a wide plate mill dedicated spray conveying roller.
At present, China still lacks a relatively complete welding system and sophisticated simulation technology, we need to develop and promote the application as soon as possible vigorously.
