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).
This type is typically found in cutting and welding applications all over the world. They work equally effectively in all orientations, and need very little maintenance. The simplest flashback arrestor consists of a metallic tube filled with iron wool, which cools the flame below the ignition temperature.
Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.

The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...
Robot welding is the use of mechanized programmable tools , which completely automate a welding process by both performing the weld and handling the part. Processes such as gas metal arc welding , while often automated, are not necessarily equivalent to robot welding, since a human operator sometimes prepares the materials to be welded.
