Pipe Welding

Welding, also known as welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. There are many energy sources for modern welding, including gas flames, electric arcs, lasers, electron beams, friction and ultrasonic waves. In addition to being used in factories, welding can also be carried out in a variety of environments, such as the field, underwater and space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken when welding. The possible harm to the human body caused by welding includes burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc.

Welding refers to a processing method in which weldments are combined by heating or pressing. According to the different welding processes, welding methods can be divided into three categories: pressure welding, fusion welding and brazing. Among them, arc welding is the most common application in fusion welding.

Fusion welding: a welding method that melts the base metal at the place to be welded, but does not apply pressure to form a weld.

Pressure welding: During the welding process, pressure (heated or not) must be applied to the weldment to complete the welding method, including solid state welding, hot pressure welding, forging welding, diffusion welding, air pressure welding and cold pressure welding.

Brazing: use a metal material with a lower melting point than the base material as the brazing filler metal, heat the weldment and brazing filler metal to a temperature higher than the melting point of the brazing filler metal but lower than the base metal melting point, and use the liquid brazing filler material to wet the base metal to fill the joints The method of connecting weldments by mutual diffusion with the base material. According to the different solders used, it can be divided into two types: brazing and soft soldering.
