FIELD: quality inspection. ^ SUBSTANCE: tested article and sample-imitator are exposed to penetrating radiation to radiographic film. Standard samples are grooves of different depth are mounted onto article and sample-imitator. At similar parameters of radiation, the article and sample-imitator are subject to initial radiation by non-filtered X-ray radiation and to secondary filtered X-ray radiation or to gamma-ray radiation without changing direction of radiation and to non-filtered X-ray radiation while changing direction of radiation. Corresponding shoots are received and subject to analysis. Quality of articles is judged from the data received. ^ EFFECT: improved truth of information; improved quality inspection of welded articles. ^ 3 dwg |
