China Manufacturer Special Steel High Quality Customized Welding Machining

Welding, also known as melting, is a manufacturing process and technology that connects metals or other thermoplastic materials (such as plastics) by heating, high temperature or high pressure. Modern welding has many energy sources, including gas flame, electric arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be carried out in various environments, such as the field, underwater and space. No matter where it is, welding may cause danger to operators, so appropriate protective measures must be taken during welding. The possible harm to the human body caused by welding includes burns, electric shocks, visual disturbances, inhalation of toxic gases, excessive ultraviolet radiation, etc.
