Abstract
Evaluation of explosion welding application was conducted for the case of cladding welded joints of aluminuim alloys 7010 and 2024 with pure aluminium. It is shown that such a protection of welds prevents stress corrosion cracking or intercrystalline corrosion.
Keywords: explosion welding, explosion cladding, friction stir welding, high-strength aluminium alloys, welded Joints, stress-corrosion cracking, intercrystalline corrosion
