The general trend of China's welding equipment for cold drawing machines is to develop towards high efficiency, energy saving, electromechanical integration and complete sets. With the further research on the application of inverter power supply to the butt welding machine, the improvement of the reliability of the power inverter component will be greatly developed. Inverter welding power supply has become an arc welding power supply due to its advantages of good welding function, fast dynamic response speed, good dynamic characteristics, high efficiency, high welding speed, multi-function, which is beneficial to complete welding mechanization, initiative and intelligence. Development direction. According to incomplete statistics, in recent years, China's inverter welding machine has been increasing in variety and specifications, and its output value and sales volume have increased at a rate of nearly 30% every year.
The butt welding machine will be developed quickly. In recent years, through the self-development, planning, introduction of technology and joint venture production of welding equipment occupations, China's active and butt welding machine technology has made great progress. The development of active and semi-active welding machines is of great significance to China's welding machine profession. It not only serves the society as an independent product, but also is widely used as a welding power source necessary for most complete special welding machine equipment in key areas of the national economy. .
Strengthen the research and development of complete sets of special welding equipment. Compared with the international level, there are certain gaps in the economic strength, technical level and management level of China's special and complete welding equipment manufacturers. The development and planning of a complete set of special welding equipment is the performance of a country's technical level, and it is necessary to strengthen operations in this area.
We should also note that users will continue to put forward higher requirements for special complete equipment. China ’s complete welding equipment manufacturing enterprises must not only make efforts in improving technology and planning level, but also in enterprise quality management and various basic parts. 3. The selection of supporting parts has invested effort in striving for new breakthroughs in special and complete welding equipment.
In terms of products, it is necessary to continue to develop complete sets of welding equipment that are urgently needed by various occupations of the national economy, and develop and develop special high-tech special equipment, such as high-power electron beam welding machines, high-power laser welding machines, and CNC cutting. Develop a complete set of welding equipment with a high starting point and a high level to ensure welding quality and reliability and provide turnkey projects.
According to the overall form of China's economic development, the annual output value of China's crude steel has broken the 100 million tons mark, and has maintained this production level for several years. In the next few years, China's steel output value will not change significantly, the demand for welding machines in domestic shopping malls is relatively stable, and the shopping mall capacity will not change much.
At present, the general situation in the domestic welding machine market is that the output value of the products exceeds the demand, the competition is fierce, and most enterprises are unable to produce and operate at a minimum.
In terms of product composition, the supply of general-purpose welding machines is in excess; the demand for high-reliability, multi-functional active and semi-active welding machines and special complete sets of welding machines and special welding machines is increasing rapidly, and some welding machines still need to be imported; Domestic and imported welding machines are basically equally divided, although domestic welding machines can be said to have an absolute advantage in terms of number, and imported products account for about half of the sales.
Although the export situation of domestic butt welding machines has increased due to the improvement of product functions and the completion of the localization of imported products, as well as the expansion of the production scale of joint ventures and foreign-funded enterprises, the export products have gradually been replaced by AC arc welding machines and rotary DC welding machines. The main shift is to active, semi-active welding machines and rebar butt welding machines, but compared with imported similar products, the gap is still very large.
