摘要

The method of surface activated joining (SAJ) was applied to reconstitution of Charpy impact specimens. SAJ makes use of friction at material surfaces in a vacuum to achieve joining without melting. This paper describes verification to apply SAJ to reconstitution of Charpy impact specimens with unirradiated reactor pressure vessel plate materials, JRQ and HSST-03. By optimizing joining parameters, heat affected zones induced by friction had a width of about 1 mm to either side of the joint. The original Charpy impact properties in the transition region were reproduced from reconstituted impact specimens with the insert length of 10 mm. The maximum temperature during joining was appreciably low at a given distance from the joining interface, compared with other conventional welding techniques.
