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. Aluminum building wiring - Wikipedia

   en.wikipedia.org/wiki/Aluminum_building_wiring

   The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...

4. Zinsco - Wikipedia

   en.wikipedia.org/wiki/Zinsco

   First developed in 1935, Alloy 6061 is a good conductor, a hard aluminum, and still a popular alloy for welding today. But in 1961, another aluminum alloy was developed: 6101. This alloy has a higher tensile strength and is the best conductor for electrical use. It is the aluminum used in the current aluminum busing of panels and load-centers.

5. Welding power supply - Wikipedia

   en.wikipedia.org/wiki/Welding_power_supply

   A welding power supply is a device that provides or modulates an electric current to perform arc welding. [1] There are multiple arc welding processes ranging from Shielded Metal Arc Welding (SMAW) to inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW) .

6. Shielded metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Shielded_metal_arc_welding

   Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding [1] or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld. An electric current, in the form of either alternating current or direct current from a ...

7. Electric resistance welding - Wikipedia

   en.wikipedia.org/wiki/Electric_resistance_welding

   Electric resistance welding (ERW) is a welding process in which metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. [1] Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. [ 2 ]
