Abstract
Comparative analysis has been performed of mechanical Joints in high-strength aluminium alloys 1420 and 1460 made by plasma and nonconsumable electrode argon-arc welding, using batch-produced welding wires SvAMg63 and Sv1201 at alternating-polarity asymmetrical current. It is shown that the strength and fracture toughness of the welds in off-centre tension of specimens strongly depend upon the thermo-physical parameters of welding.
Keywords: plasma welding, aluminium-lithium alloys, welded joints, weld metal, mechanical properties
