description: This work is devoted to the study of the causes of cracks in the assembly unit "Sleeve" as a result of the welding operation and the subsequent operation of strength testing. The work was carried out at the scientific center "Concern "Marine underwater weapons â "Gidropribor". In which the rejected assembly unit "Sleeve" was cut and microscopic studies of the area within which the crack passes were carried out, analyses of the base metal as well as the weld metal were carried out. Measurements of the hardness of various metal sections in the crack area were carried out, during which a significant difference in the hardness of the base metal in the crack area was detected. The following measures are proposed to eliminate the appearance of cold cracks in the form of developed technological equipment for assembly for welding and for testing, the optimal welding method and modes ensuring de-fect-free production of parts are selected. The optimal welding equipment for the assembly and welding of this assembly unit has been selected.
