Laser welding of austenitic ferrofluid container for the KRAKsat satellite

Abstract: The production of a ferrofluid container, intended for use in the KRAKsat (CubeSat type) satellite in space conditions, is presented. Mechanized laser beam welding for AISI 316L stainless steel test joint and container prototype was developed and tested. The welded test joints were examined by non-destructive visual, penetration and radiographic testing and destructive testing by macro- and microscopic examination, static tensile test, static bending test, and hardness measurements. The welded container protot… Show more

“…The advantage of the process is that it provides a large amount of energy in the very short time of the laser pulse. The characteristics of the laser treatment include the minimization of chemical pollution and the leveling of oxidation processes [ 29 , 30 , 31 , 32 ].…”

“…John C. et al [1] discovered the welded metals with an FN of 3-7 were both resistant to solidification cracking and had good fracture toughness, at extremely low temperature, in the industry. The morphology of ferrite will also affect its corrosion resistance and mechanical properties [6][7][8]. Hence, FN has a serious influence of the mechanical properties of austenitic stainless steel.…”

“…Performing a hybrid modification consisting of coating deposition followed by laser modification makes it possible to improve material properties [11]. The validity of the laser as a heat source is related to its widespread use for welding and surface modification [12]. The use of a laser beam for modification is advantageous due to the reproducibility of the process and the possibility of precise determination of the modification area [13].…”
