The Australian Nuclear Science and Technology Organisation (ANSTO) at Lucas Heights, have two neutron instruments: KOWARI and DINGO that can be useful tool in modern welding assessment. Both instruments provide non-destructive characterisation techniques for modern materials, engineering and structural integrity investigations. The primary function of the KOWARI instrument is the determination of residual stresses within the interior of bulk engineering components and test samples, in particular for the development of modern engineering welding processes as well as post processing (e.g. post weld heat treatment, peening) and variety of structural integrity investigations. DINGO is a neutron radiography and imaging beamline used to assessing defects and dimensional tolerance of internal features engineering components well suited for thick and complex’s weldments. In this paper an overview of possibilities and recent developments on both instruments are presented.
