RESISTANCE OF WELDS ON THIN-SHEET ALUMINIUM ALLOYS TO INITIATION AND PROPAGATION OF SERVICE CRACKS

Abstract
Resistance friction stir and TIG welds on ductile low aluminium alloys and high-strength multi-component aluminium alloys 1.8 mm thick to initiation and propagation of cracks was determined by subjecting specimens comprising stress raisers to tension. It was shown that the welds made without metal melting have a higher resistance to service cracks.
