kaarkeevitus, kus pealiskuti asetsevad detailid keevitatakse kokku üksikute punktidena sulatusega läbi ülemise detaili; kasutatakse nii TIG- kui MIG-punktkeevitust (vt TIG-punktkeevitus, MIG-punktkeevitus), a spot welding process made by an arc welding process; it is basically arc welding process (gas tungsten arc welding (GTAW)/TIG-welding) or gas metal arc welding (GMAW)/MIG-welding) that produces coalescence by an heat of electric arc (see: gas tungsten arc spot welding/GTA spot welding, gas metal arc spot welding/GMA spot welding)
