2. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   To supply the electrical energy necessary for arc welding processes, a number of different power supplies can be used. The most common classification is constant current power supplies and constant voltage power supplies. In arc welding, the voltage is directly related to the length of the arc, and the current is related to the amount of heat ...

3. Radio-frequency welding - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_welding

   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.

4. Spot welding - Wikipedia

   en.wikipedia.org/wiki/Spot_welding

   When welding a common combination like 1.0 + 1.0 mm sheet steel, the voltage between the electrodes is only about 1.5 V at the start of the weld but can fall as low as 1 V at the end of the weld. This decrease in voltage results from the reduction in resistance caused by the workpiece melting.

5. Diffusion bonding - Wikipedia

   en.wikipedia.org/wiki/Diffusion_bonding

   Diffusion bonding or diffusion welding is a solid-state welding technique used in metalworking, capable of joining similar and dissimilar metals. It operates on the principle of solid-state diffusion, wherein the atoms of two solid, metallic surfaces intersperse themselves over time.

   The aluminum foil allows the flame to stay even and continuously radiate heat, as well as retain heat to help melt the leftover wax. Ellie Martin Cliffe, executive editor at our sister site, Taste ...

8. Ultrasonic welding - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_welding

   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.
