Welding machines are important process equipment in modern industry and are widely used in the industry. Welding machines in China are mainly divided into plastic welding machines and metal welding machines based on materials. Currently, they are developing from single machine welding automation equipment to welding automation production lines. The following is the definition and classification analysis of the welding machine industry.
After more than 50 years of development, China's welding machine industry has formed a number of enterprises with a certain scale. Its products mainly include: manual arc welding machines, resistance welding machines, semi-automatic arc welding machines, special welding machines, and various special complete sets of welding equipment and welding assembly production lines, which can basically meet the needs of the national economy.
According to the analysis of the welding machine industry, the China Welding Machine Association's statistical data from 41 domestic welding and cutting machine enterprises last year showed that the total industrial output value reached 66.117341 million yuan, a year-on-year increase of 15.31%, and a decrease of nearly 16 percentage points in growth rate. Among them, the completed export delivery value reached 1200.626 million yuan, a year-on-year increase of 18.89%. Although the growth rate of the total output value indicator is decreasing, the ability of welding machine enterprises to cope with environmental changes has significantly improved.
Experts from the association also stated that what is stable and changing this year is that the product structure of the industry will be adjusted. From the market demand forecast, it will change with the development of welding technology and process, as well as the improvement of production mechanization and automation level, especially the proportion of various products, such as AC arc welding machines, has significantly decreased. The demand for automatic and semi-automatic welding machines, especially CO2 welding machines, and specialized complete sets of welding machines has significantly increased. Let's take a look at the definition and classification of the welding machine industry from the following.
There are many types of welding machines, including single point single function, single point dual function, and single point multifunctional (this type of welding machine only has one welding head, and can perform welding at any angle between 90 ° and 180 ° after changing the form of the positioning plate). There are also two, three, four, and even six point welding machines and four angle welding machines. Different types of welding machines have different welding functions and work efficiency.
Welding machines are mainly divided into two types based on materials: plastic welding machines and metal welding machines. The definition and classification analysis of the welding machine industry mainly involve technologies such as ultrasonic, high-frequency, plasma, electric heating, rotary, etc.
1) Plastic welding machine: Plastic welding machine is used for welding thermoplastic engineering plastic sheets or products such as polyethylene, polypropylene, nylon, etc. During operation, plastic welding rods are melted and sprayed out, causing the welded workpiece to fuse and bond with them. It is widely used in welding and repairing plastic equipment, laying plastic flooring, connecting plastic pipes, sealing plastic bottles, and other operations. 2) Metal welding machine: Metal welding machines mainly weld metal materials.
The technical level of welding machines is an important reflection of the national scientific and technological level, directly determining the technical level of major core equipment in the country. There are many enterprises in the welding machine industry in China, and the vast majority of them have strong development capabilities. It is expected that the proportion of inverter welding machines will reach around 60% in the next three to five years, and the market capacity of inverter welding and cutting in China will exceed 36 billion yuan by 2023. The significant growth of the inverter welding machine market will also drive the development of the welding and cutting equipment industry. The above is the definition and classification analysis of the welding machine industry.
