Gouging requires specific tools and equipment designed for metal removal. These may include carbon electrodes, gouging torches, air carbon arc gouging systems, or plasma gouging equipment. The tools generate intense heat and produce a focused arc or plasma stream to melt and remove the metal.

Welding requires specific tools and equipment depending on the welding process used. Common welding techniques include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), and flux-cored arc welding (FCAW). Each process may require different types of welding machines, welding electrodes, shielding gases, or consumables.
