Abstract

This paper presents the results of the experimental research regarding laser microwelding parameters for sealed stainless steel capsules used for radioactive sources. The investigations took into consideration the metal loss, penetration of the radiation, geometric size of the welding area, and the relation between these measured parameters and laser parameters.
