What are the welding methods?

Hello, I'm glad to answer your question:

According to the characteristics of energy and technology, welding can be divided into three categories: fusion welding, pressure welding and brazing, and each category is divided into different welding methods.

1, fusion welding is divided into arc welding, gas welding, thermite welding, electroslag welding, electron beam welding and laser welding.

2. Pressure welding is divided into resistance spot welding, resistance butt welding, ultrasonic welding, explosion welding, diffusion welding, friction welding and high frequency welding.

3. Brazing includes flame brazing, induction brazing, furnace brazing, salt solution brazing and electron beam brazing.

Extended data

Welding, also known as fusion, is a manufacturing process and technology to connect other thermoplastic materials such as metal or plastic by heating, high temperature or high pressure.

Modern welding has many energy sources, including gas flame, arc, laser, electron beam, friction and ultrasonic wave. Besides being used in factories, welding can also be carried out in various environments, such as outdoor, underwater and space. No matter where, welding may bring danger to operators, so appropriate protective measures must be taken during welding. Welding may cause harm to human body, including burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc.
