A method of metal weld in which pressure is applied (heated or unheated) to the weldment to make it bond together. Common pressure welding methods include resistance contact welding, diffusion welding, friction welding, ultrasonic welding, explosive welding, etc. In addition, rotating arc or gas flame rotating at high speed in the magnetic field is used to heat the end, and then pressurize to realize rotary arc welding and gas combination welding of plastic weld; Magnetic pulse welding, which uses the interaction of pulse magnetic fields to produce the effect similar to explosive welding; The cold pressure welding of weld is realized only by pressure at room temperature; Utilizing water to condense into ice and generate expansion force to achieve room temperature pressure welding, such as ice pressure welding.
