Peculiarities of laser welding of thin parts of aerospace equipment


In this paper, the laser welding methodology technological process optimization of shallow thickness aerospace constructions was considered. The methodology consists in selecting of multivariate iterative process parameters. Using this methodology can significantly reduce the technological preparation time of production and the proportion of experimental research. Experimental confirmation was work on laser butt welding parts for shallow thicknesses, material welded samples - nickel-based alloys. Work was carried out to determine the chemical composition of the alloy samples, modeling and development of a special device for welding products. Laser welding is carried out on the process plant includes a pulsed solid-state laser YAG:Nd with a wavelength of 1,06 microns. On the basis of the developed method of optimization parameters were selected welding process. According to the results of work defines the quality of the welded joint specimens using metallographic examination of the weld, and testing of mechanical properties of butt weld specimens were performed, the tensile strength was determined. The developed method of process optimization of laser welding of parts of small thickness allows for high quality welds free of defects in the surface layer.
