kaarkeevituse protsesside/operatsioonide rühma üldnimetus, mille puhul sulava elektrooditraadi ja keevisvanni vahelist keevituskaart kaitstakse sinna juhitud gaasiga; kasutatud kaitsegaasi alusel sageli eristatakse kaarkeevitust [sulavelektroodiga] inertgaasis (MIG-keevitus) ning kaarkeevitust [sulavelektroodiga] aktiivgaasis (MAG-keevitus) (vt MIG-keevitus; MAG-keevitus), an arc welding process that produces coalescence of metals by heating them with an arc between a continuous filler metal electrode and the workpieces; shielding is obtained entirely from an externally supplied gas; based on the shielding gas frequently a differentation is made between metal inert gas welding (MIG-welding) and metal active gas welding (MAG- welding) (see: MIG-welding; MAG-welding)
