Abstract
Volt-ampere characteristics of the steady and impulse arc in mixtures of different inert gases and features of weld formation and geometry are analyzed. A fundamental possibility and cost-effectiveness of application of helium-neon mixtures for protection of the welding zone is demonstrated.
Keywords: arc welding, aluminium alloys, consumable electrode, inert gases, gas mixtures, volt-ampere characteristics, weld parameters, defects
