Abstract
Technological capabilities for increasing strength and fracture toughness of welded joints on aluminium-lithium alloys are considered in terms of ensuring the reliability and safe operation of structures. It is shown that the use of low heat input in welding and new modified welding wires with a decreased content of harmful impurities provides a sufficient level of mechanical properties in all structural zones of the welded joint.
