dc.description.abstract© 2022 Author(s).The paper analyzes the properties and structure of welded joints obtained on a laser machine for butt welding of thin sheets for an alloy of the Al-Li system. To assess the compliance of welded joints obtained using laser technology with the requirements of technical conditions, mechanical tests of alloy 1420 with a welded seam were carried out. Despite the undoubted advantages of using laser welding when installing structures made of aluminum-lithium alloys, the resulting welded joints do not meet the requirements of technical conditions, namely, the imperfect structure of the welded joint significantly reduces their ductility. Ultrasonic impact treatment method made it possible to increase the ductility of welded joint by an average of 20%.
