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.
However, it is one of the easier materials to weld using ultrasonic welding because it is a softer metal and thus a solid-state weld is simple to achieve. [12] Since aluminum is so widely used in the aerospace industry, it follows that ultrasonic welding is an important manufacturing process.
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.
During the pause between the two pulses, the electrodes will come closer and make better contact. During spot welding, the large electric current induces a large magnetic field, and the electric current and magnetic field interact with each other to produce a large magnetic force field too, which drives the melted metal to move very fast at a ...

Aluminum foil is a household item that has about a million uses. We’ll highlight some amazing money-saving uses in this episode of The Saving's Experiment! Unexpected uses for aluminum foil
Overhead stick welding. Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion.
The most frequently used cathode is made of a tungsten strip, about 0.05 mm thick, shaped as shown in Figure 1a. The appropriate width of the strip depends on the highest required value of emission current. For the lower range of beam power, up to about 2 kW, the width w=0.5 mm is appropriate.
