plasmakeevitamine sulamatu elektroodi ja suudmiku vahel põleva kokkusurutud plasmakaare abil (vt plasmakeevitus; vrd plasmakaarkeevitus), an arc welding process that produces coalescence of metals by heating them with constricted arc between an electrode and the constricting nozzle (non-transferred arc); the workpiece is not in the electrical circuit; the heat generated from non-transferred arc is more dispersed and there is no risk of contamination from the electrode materials as compared to plasma arc welding with transferred arc (see: plasma arc welding; compare: plasma arc welding with transferred arc)
