Radio-frequency welding, also known as dielectric welding and high-frequency welding, is a plastic welding process that utilizes high-frequency electric fields to induce heating and melting of thermoplastic base materials. [1] The electric field is applied by a pair of electrodes after the parts being joined are clamped together.
Ultrasonic welding of thin metallic foils. The sonotrode is rotated along the weld seam. Ultrasonic welding is an industrial process whereby high-frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid-state weld.
It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact. Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used.
Upon collision with atoms in solids their kinetic energy transforms into heat. EBW provides excellent welding conditions because it involves: Strong electric fields, which can accelerate electrons to high speed that carry high power, equal to the product of beam current and accelerating voltage. By increasing the beam current and the ...
A flat to flat and flat to groove joint used in implant induction welding. Weld time will vary based on the joint size, the volume of susceptible implant material, and the power and frequency. Cycle times can be very fast since no preheating is needed, and heat generation happens exclusively at the weld joint. This also benefits the cooling time.
Today we have an exclusive on new AI-powered video capabilities from Vimeo—and with it a conversation I think encapsulates a lot of what companies are going through in this current moment of ...
Induction welding is a form of welding that uses electromagnetic induction to heat the workpiece. The welding apparatus contains an induction coil that is energised with a radio-frequency electric current. This generates a high-frequency electromagnetic field that acts on either an electrically conductive or a ferromagnetic workpiece.
The electrical energy for the percussion welding can be supplied by a transformer, as alternating current (or rectified), or by the discharge of capacitors.Because of the short duration of the arc and of the fact that all of the weld energy comes from this arc, the electrical resistance of the parts to be welded does not affect the amount of heat generated at the weld and substances of ...
