Welding machines are mainly divided into two types: plastic welding machines and metal welding machines. The technologies applied are: ultrasonic, high frequency, plasma, electrothermal, rotary, etc.
Among them, the plastic welding machine is used for welding thermoplastic engineering plastic sheets or products such as polyethylene, polypropylene, polypropylene and nylon. During operation, the plastic electrode is melted and melted, and the workpiece to be welded 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 so on.
Metal welding machines mainly weld metal materials.
