The general trend of welding equipment is to develop towards high efficiency, energy saving, mechatronics and complete sets. Butt welding machine With further research on the application of inverter power to active and semi-active welding machines, the reliability of power inverter components is improved, and butt welding machines will be greatly improved. The welding power source of butt welding machine has good welding function, fast dynamic response speed, good dynamic characteristics, high power, high welding speed, and multiple functions, which is conducive to the completion of the benefits of welding mechanization, automation and intelligence. It has become an direction of development of arc welding power source. According to incomplete statistics, in recent years, while the types and standards of welding machines have been continuously added, their output value and sales have increased at a rate of nearly 30% each year.
Active and semi-active welding equipment, especially high-efficiency and energy-saving butt welding machine will be developed rapidly. In recent years, the skill level of butt welding machines has been greatly developed through the self-development, research and development of welding equipment, the introduction of skills and joint venture production. The development of active and semi-active welding machines is of great significance to the operation of electric welding machines. It not only serves the society as an independent product, but also is widely used in important areas of the national economy as a set of special and necessary welding equipment.
