2. Induction welding - Wikipedia

   en.wikipedia.org/wiki/Induction_welding

   The apparatus used for induction welding processes includes a radio frequency power generator, a heating station, the work piece material, and a cooling system. The power generator comes in either the form of solid state or vacuum tube and is used to provide an alternating current of 230-340 V or a frequency of 50–60 Hz to the system.

3. Electrofusion welding - Wikipedia

   en.wikipedia.org/wiki/Electrofusion_Welding

   A control box takes electrical power from a generator and converts it into an appropriate voltage and current for electrofusion joining. This provides consistent energy input for each application. The most common input voltage for electrofusion welding fittings is 39.5V, as it provides the best results without risking operator safety.

4. Fusion welding - Wikipedia

   en.wikipedia.org/wiki/Fusion_welding

   Arc welding is one of the many types of fusion welding. Arc welding joins two pieces of metal together by using an intermediate filler metal. The way this works is by completing an electrical circuit to create an electrical arc. This electrical arc is 6500 °F (3593 °C) in its center. [3]

5. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   One of the most common types of arc welding is shielded metal arc welding (SMAW), which is also known as manual metal arc welding (MMAW) or stick welding. An electric current is used to strike an arc between the base material and a consumable electrode rod or stick. The electrode rod is made of a material that is compatible with the base ...
