Welding, also known as welding, welding, is a kind of heating, high temperature or high pressure in the way of bonding metal or other thermoplastic materials such as plastic manufacturing process and technology. Welding through the following three ways to achieve the purpose of
assembly line aluminum profiles joint:
1. Fusion welding - heating to engage the workpiece to form a partial melting pool, pool cooling and solidification joint, when necessary to join the filler auxiliary, it is suitable for all kinds of metal and alloy welding processing, so that assembly line aluminum profiles welding without pressure.
2. Pressure welding - The welding process must apply pressure to the assembly line aluminum profiles for the processing of various metal materials and some metal materials.
3. Brazing -- The metal material with a lower melting point than the base metal is used as a filler metal. The liquid filler metal is used to moisten the base metal, fill the joint gap, and realize the link welds by mutual diffusion with the base metal. Suitable for welding of various materials, but also suitable for welding of different metals or heterogeneous materials.
There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasonic waves. In addition to its use in assembly line aluminum profiles connection, welding can be performed in a variety of environments, such as the wild, underwater, and space. Welding anywhere can be dangerous to the operator, so proper precautions must be taken when welding. Possible injuries caused by welding include burns, electric shock, visual impairment, inhalation of toxic gases, and excessive ultraviolet exposure.
