Abstract
Experiments on using neon and its mixtures with argon as a shielding gas in non-consumable electrode welding are considered. Data are obtained on weld formation, penetration and also volt-ampere characteristics at direct and alternating currents. The feasibility of using neon separately or in mixtures of gases for protection of aluminium alloy welding zone is shown.
Keywords: arc welding, non-consumable electrode, shielding gases, aluminium alloys, volt-ampere characteristics, weld formation
