PROCESS TESTING ARTICLES WITH OPEN SPACE FOR TIGHTNESS WITH CORRECTION OF DEFECT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2003 - IPC

FIELD: testing equipment, tightness test of aluminum alloy castings with open space. SUBSTANCE: process for detection of defects in articles with open space and their correction is executed by supply of compressed air, defect proper is controlled by means of liquid and point of defect is welded afterwards. Article is attached to pressing flange of device, is positioned in housing. liquid is poured into space of part through window in flange and compressed air is fed into space of housing. When point of bubble formation is located device with article is tilted for flow of liquid along slope and opening of defect, thereupon defect is corrected. Device for implementation of this process includes sealing and fixing elements, working liquid, pipe union to supply compressed air, housing for placement of article in which pipe union and ball bearing are installed, pressing flange with window made over internal perimeter of article. EFFECT: simplified design, functional convenience of device and reduced labor input to test. 2 cl, 1 dwg
