Claims (2)
- 溶接鋼管の溶接部を複数の超音波探触子で探傷し、溶接部の品質を検査する方法において、超音波探触子から超音波を送受信する方向は、溶接鋼管長手方向に対して直角方向、溶接鋼管長手方向に対して所定の角度をもった方向、溶接部の真上における溶接鋼管長手方向に沿う方向のうちの少なくとも2方向であり、この各方向において2つ以上の超音波探触子で超音波の反射信号を受信した時に、きず有りと判定して、警報により検査員にきずが検出されたことを教示し、続いて各超音波探触子で信号を検知した結果をレコーダチャートに出力させることで、検査員にきずが検出されたことを教示し、その検出位置を再探傷位置で停止させ、再検査によりきずを確認することを特徴とする溶接鋼管溶接部の品質検査方法。
- 請求項1に記載の溶接鋼管溶接部の品質検査方法において、溶接部のきずを検知した時、きず検出位置に、鋼管周方向に溶接部を跨いで線状にマーキングを施し、このマーキング位置を再検査することを特徴とする溶接鋼管溶接部の品質検査方法。
