From this year's various exhibitions, you can find several characteristics of foreign welding equipment at this stage: high precision, high quality, high reliability, digitalization, intelligent control, large-scale, integration, and multi-function. Domestic welding parts suppliers is developing in the direction of efficient, automated, intelligent, energy-saving, and environmentally-friendly welding in terms of output composition and technology development direction.
Welding equipment is a large-volume and wide-ranging product, with a large variety and complete specifications, and is gradually approaching the international level. The market share of high-efficiency, energy-saving, material-saving, and consumption-reducing products will further expand. It is necessary to comply with market requirements, adjust product structure and improve product quality, and it is advisable to vigorously develop inverter welding power sources and automatic and semi-automatic welding machines, especially high-efficiency energy-saving carbon dioxide welding machines.
Resistance welding technology uses medium and high power as the main research content and development direction. Microcomputer control quality monitoring of resistance welding, inverter resistance welding technology, intelligent and expert systems, flexible resistance welding equipment, welding resistance robots, etc. are important research contents and professional production directions. The development of resistance welding machines, which are especially suitable for welding requirements of coating materials, aluminum alloy materials, and precision parts, has attracted more attention.
The development of test technology and test equipment will help promote the improvement of enterprise processes and technology.
Electromagnetic compatibility technology will be popularized and applied in welding equipment. Electromagnetic pollution has been identified as the fifth-largest source of environmental pollution, and electromagnetic environmental problems are becoming increasingly prominent. The welding equipment industry urgently needs low energy consumption and green products. National mandatory standards "Electromagnetic Compatibility Requirements" and "Evaluation of Injuries to Operators by Electromagnetic Fields of Welding Equipment" are based on electromagnetic compatibility standards, such as evaluation criteria for welding equipment that affects operators, and will be changed after they are issued. Due to incomplete testing indicators, domestic products cannot reach the international market on a large scale.
