Welding: also known as welding, welding, is a way to heat, high temperature or high pressure bonding metal or other thermoplastic materials such as plastics manufacturing technology and technology. Welding through the following three ways to achieve the purpose of bonding:

1, welding - to heat the parts to be joined so that the partial melting of molten pool, the pool after cooling and solidification will join, if necessary, can be added to fill support, it is suitable for a variety of metals and alloys welding, without pressure.

2, pressure welding - the welding process must exert pressure on the weldment, belonging to a variety of metal materials and some metal materials processing.

3, brazing - the use of metal materials than the base metal melting point low as a filler metal, the use of liquid solder wetting the base metal, fill joint gap, and mutual diffusion with the parent material to achieve the link weldment. Suitable for a variety of welding materials, but also for different metals or dissimilar materials welding.

Modern welding has many sources of energy, including gas flame, electric arc, laser, electron beam, friction and ultrasound. In addition to being used in the factory, welding can also be carried out in a variety of environments, such as in the wild, underwater and in space. Wherever welding can be dangerous to the operator, proper precautions must be taken during welding.
