A welding technique that uses the energy from the electric arc produced between an electrode and the metal workpiece as its source of heat.
A technique in which metal is welded with heat generated by an electric arc struck between two electrodes or between one electrode and the metal workpiece. See also fusion welding, oxyacetylene welding, and resistance welding
A group of welding processes wherein the metal or metals being joined are coalesced by heating with an arc, with or without the application of pressure and with or without the use of filler metal.
A welding process widely used for do-it-yourself repairs in which the welding current is generated by a transformer, and the circuit is closed when the electrode held in the welding rod holder touches the metal surface; the electrode burns off as the rod holder is moved along
A fusion welding process that uses electricity to generate the heat needed to melt the base metals.
A group of welding processes wherein coalescence or complete fusion is produced by heating with an electric arc.
A process of joining to pieces of metal by melting them together at their interface with a continuous electric spark and adding a controlled additional amount of molten metal from a metallic electrode.
(See electric arc welding.)
A form of metal welding done by using the heat created as an electric arc jumps from an electrode to metal.
Arc welding refers to a group of welding processes that use a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding region is sometimes protected by some type of inert or semi-inert gas, known as a shielding gas, and/or an evaporating filler material.
