The best high frequency welding machine suppliers is davison-machinery's High Frequency Welding Machine: also known as welding, welding, is a kind of heating, high temperature or high pressure way bonding metal or other thermoplastic materials such as plastic manufacturing process and technology. Welding through the following three ways to achieve the purpose of bonding:
1, welding - heating to join the workpiece to make the local melting of the molten pool, pool cooling after solidification joint, if necessary, can be added to fill the filler auxiliary, it is suitable for all kinds of metal and alloy welding process, without pressure.
2, pressure welding - welding process must be applied to the pressure of welding parts, metal parts are a variety of metal materials and processing.
3, brazing - the use of metal materials than the low melting point of the parent metal as filler metal, the use of liquid solder wetting the base material, filling the joint gap, and the mutual diffusion of the base material to achieve the link weldment. Suitable for welding a variety of materials processing, but also for different metals or different types of welding materials processing.
Modern welding energy sources are many, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to use in the factory, the welding can also be carried out in a variety of environments, such as the field, underwater and space. Wherever welding is likely to pose a risk to the operator, appropriate precautions must be taken when welding is to be carried out. Welding to the human body may cause injury, including burns, electric shock, visual impairment, inhalation of toxic gases, ultraviolet radiation excessive.
