FIELD: instrument making.
SUBSTANCE: suggested invention is related to the field of testing equipment and is intended for tightness testing of welded products with internal joined channels and cavities, for instance transformer bodies with corrugated walls. Technical result is achieved by the fact that test bench comprises open reservoir with liquid, device for supply and exhaust of gas under excessive pressure into internal channels and cavities, cover for product sealing, device for item fixation. Besides according to invention, device for fixation of item is installed with the possibility of fixation to sealing cover and is arranged in the form of bracket with grip installed on column, which interacts with lifting-lowering mechanism and mechanism of sealing cover rotation with item around column.
EFFECT: simplified testing with improved accuracy of test results.
