“…Experience in the manufacture and operation of multicomponent heat-resistant alloys for aerospace products has necessitated the strengthening of quality requirements for such welded joints [1][2][3][4][5]. The quality of heat-resistant alloy welds is usually assessed using the requirements of EN ISO 13919-1:2019 "Electron and laser-beam welded joints -Requirements and recommendations on quality levels for imperfections -Part 1: Steel, nickel, titanium and their alloys".…”

In this study, the method of determining the influence of laser welding parameters on the quality provisions of welded joints made with multicomponent heat-resistant alloys was developed. The regularities of the formation of the welded joint structure of multicomponent heat-resistant alloys obtained by laser welding have been studied. The causes and methodological approaches to eliminate defects in the form of hot cracks were identified. Keywords: laser welding, multicomponent alloys, heat-resistant alloys, welded joints, quality
