Ultrasonic inspection of weld cylinders of candidate nuclear used fuel container materials (copper, titanium grades 2 and 12, stainless steel 316, Inconel 625, Hastelloy C-276) using immersion longitudinal waves showed that titanium grades 2 and 12 exhibited essentially isotropic behaviour (little beam skewing). The other materials all showed significant aniso-tropy, which will probably present inspection problems for final closure welds. Metallography showed that the stainless steel, Inconel and Hastelloy all had long columnar grains, but that the copper showed columnar grains round each weld pass with equiaxed grains in the centres. Altering weld interpass temperatures produced no consistent trend in ultrasonic behaviour.
