- Abstract
Structures for tube - tube sheet welded joints (TTSWJ) and schemes for x-radiographic monitoring are considered. Monitoring problems connected with further development of heat exchanger structures, and their solution, are defined. Description of a developed and manufactured test example of an automated device for TTSWJ x-radiographic monitoring with programmed control is provided. The device makes it possible to monitor for one exposure joints with a diameter from 8 to 20 mm. The manual operating part includes placing an unexposed film holder into the device and its removal after exposure. Fulfillment of exposure conditions (voltage, current, etc.) and subsequent passage around a TTSWJ is accomplished automatically by a prescribed regime. The test example is tested on TTSWJ specimens and models made of titanium and stainless steel; results are provided.
