What Are the Different Types of Welding Power Supply?
The welding power source refers to the power source of CO2 gas shielded welding. It adopts flat characteristics or slow-down external characteristics. The no-load voltage is 38 ~ 70V. The arc has a strong self-regulating effect, a large short-circuit current, an easy arc initiation, and no wire sticking. During operation, you will feel the arc calm, soft, elastic, and small splash. [1]

- Welding, also known as welding, butt welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastic by heating, high temperature or high pressure. Welding achieves the purpose of joining in the following three ways:
- 1. WeldingHeating the workpieces to be welded to locally melt them to form a molten pool. After the molten pool is cooled and solidified, it will be joined. If necessary, a molten filler can be added to assist. pressure.
- 2. Pressure welding-The welding process must apply pressure to the weldment, which belongs to the processing of various metal materials and some metal materials.
- 3. BrazingUse a metal material with a lower melting point than the base metal as the brazing material, use the liquid brazing material to wet the base material, fill the gap between the joints, and mutually diffuse with the base material to achieve the link welding. Suitable for welding of various materials, but also suitable for welding of different metals or dissimilar materials.
- There are many sources of energy for modern welding, including gas flames, arcs, lasers, electron beams, friction, and ultrasound. In addition to being used in the factory, welding can be performed in a variety of environments, such as field, underwater, and space. Wherever possible, welding can be dangerous to the operator, so proper precautions must be taken when welding. Possible injuries to the human body from welding include burns, electric shock, visual impairment, inhalation of toxic gases, and excessive ultraviolet radiation.
