Welding machines are used in many factories and enterprises. Many people may not have a special understanding of welding machines. In this article, we will briefly introduce welding machines and related knowledge. I hope it will be helpful to you after reading this article.

The meaning of welding machine.
There are many types of welding machines, including single-point single-function, single-point dual-function, and single-point multi-function (this type of welding machine also has only one welding head. After changing the form of the positioning plate, it can be used for any angle between 90° and 180° Angle of welding). There are also two-point, three-point, four-point and even six-point welding machines and four-point welding machines. Different types of welding machines have different welding functions and work efficiency.
Welding is the process of joining metal parts with various fusible alloys (solder). The melting point of solder is lower than that of the material to be welded, so that the part will not be melted, through the intermolecular contact on the surface of the part to complete the welding.
Welding can be divided into soft welding and hard welding. The temperature of soft welding is lower than 450℃, and the temperature of hard welding is higher than 450℃. Hard welding is usually used for metals such as silver, gold, steel, copper, and its welding point is much stronger than soft welding, and its shear strength is 20 to 30 times that of soft welding. The above two types of thermal connections usually use the term soldering, because in both cases molten solder is written into two elongated gaps between the clean and close solid metal surfaces of the device.
Welding machines are mainly divided into two types according to materials: plastic welding machines and metal welding machines. The applied technologies mainly include: ultrasonic, high frequency, plasma, electric heating, rotary, etc.
Among them, the plastic welding machine is used to weld polyethylene, polypropylene, polypropylene, nylon and other thermoplastic engineering plastic sheets or products. During operation, the plastic welding rod is melted and sprayed out, and the welded workpiece is fused and bonded. It is widely used in the welding and maintenance of plastic equipment, plastic floor laying, plastic pipe connection, plastic bottle sealing and other operations.
