The new energy power system refers to the power system with renewable energy as the main energy source, including solar energy, wind energy, hydro energy, etc. The construction and operation of new energy power systems require a large number of welding technology support, such as the manufacture of wind turbines, the manufacture of solar panels, the construction and maintenance of transmission lines, etc., all require the application of welding technology.

In recent years, with the advancement and development of new energy technology, the manufacturing level of new energy vehicles is also improving. As an important part of the automobile manufacturing industry, the new energy vehicle manufacturing industry is no longer satisfied with the traditional welding technology, but is replaced by the injection of new technologies. Therefore, the application of emerging welding technologies such as friction stir welding, cold metal transition welding, and laser welding in the new energy vehicle industry is analyzed, and the development trend of welding technology in the new energy vehicle industry is prospected.

With the gradual development of China's construction steel structure technology, the continuous optimization of steel, high-strength steel and ultra-high-strength steel has been vigorously promoted and applied. At the same time, the welding design technology of the past will also be severely affected. More requirements are put forward for steel structure welding technology. In the construction steel structure, welding as the main connection method, its importance is more and more immeasurable. Therefore, in order to comply with the trend of rapid development of steel structure, the improvement of welding level has become a key research issue in the industry, and welding technology will also develop to more advanced technology.

The demand for railway processing efficiency is more prominent, and Bocast has a unique leadership position in the revolutionary energy industry, especially in engineering welding materials, industry applications and process knowledge, as well as global existing technology support and distribution
