Exothermic simply means a process that produces heat. Includes arc welding, oxy-acetylene etc. The Cad-weld process for example used in grounding systems produces heat by chemical means.

Exothermic: characterized by or formed with evolution of heat.

Welding: to unite (metallic parts) by heating and allowing the metals to flow together or by hammering or compressing with or without previous heating.
