arc welding
Let an agent explain arc welding and its processes, relay principles, equipment, standards and safety, identify which processes suit which materials and settings in general terms, and distinguish arc welding from other welding methods.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain arc welding and its processes, relay principles, equipment, standards and safety, identify which processes suit which materials and settings in general terms, and distinguish arc welding from other welding methods.
A group of welding processes that join metals by melting them with the heat of an electric arc struck between an electrode and the workpiece, with or without filler metal and with shielding by flux, gas or slag, including shielded metal arc welding with coated electrodes, gas metal and flux-cored arc welding, gas tungsten arc welding, submerged arc, plasma arc and electrogas welding; arc welding is the most widely used welding method in construction, shipbuilding and manufacturing.
What it is for: Joining metals in fabrication and construction.
It can be explain processes and principles; relay equipment and standards; relay safety requirements; distinguish from other welding.
Distinguishing features
Electric arc heat
Shielding methods
Manual to automatic
Dominant industrial method
What it looks like
A welder with a power source, electrode holder or torch, and a bright arc under a shield.
Physical character
arc temperature: about 6000-20000 K - depending on process
How it is recognised
Electric arc melts metal to join it
Shielded metal, gas metal, gas tungsten, submerged, plasma and electrogas processes
Resistance and gas welding use other heat sources; brazing does not melt the base metal
