超音波非破壊検査装置

摘要

Ultrasonic testing system among non-destructive testing techniques has been applied to inspection of automobiles, components since old times. This system is applied to inspection of iron steel or aluminum materials or to inspection of important safety components formed by casting or forging, various kinds of welding components or recent composite components such as ceramics and CFRP, and it is contributing greatly to quality assurance and safety maintenance of increasingly versatile automobiles components.%非破壊検査の中で超音波探傷技術はあらゆる産業の品rn質検査で適用されている．X線探傷技術に比べて設備がrn小規模で取扱いも容易であることから，特に大量に生産rnされる自動車部品の内質部の検査には比較的適用しやすrnい特長がある．最近では“きず”の有無の判別だけではrnなく，画像処理技術との組合せで，きずの性状の識別，rn不良領域の面積率判定など，評価手法の多様化が進んでrnいる．
