探傷儀

對焊風險的超聲波橫波探傷中，通常會用到DAC曲線，對缺陷當量大小常用DAC±dB或SL±dB的方法來表示。而對鍛、鑄件的超聲波縱波探傷中，通常會用到AVG曲線。AVG曲線是描述規則反射體的距離、回波高度及當量大小之間關系的曲線。AVG曲線按照通用性分為通用AVG和實用AVG；按照波形不同分為縱波AVG和橫波AVG；按照反射體不同分為平底孔AVG和橫孔AVG。DAC距離—波幅曲線是描述某一確定反射體回波高度隨距離變化的關系曲線。AVG曲線采用歸一化距離A和歸一化缺陷當量大小G來表示。當A<1時，由于波的干涉，使平底孔回波聲壓出現極大值；在A<3的區域內，由于理論公式不適用，因此該區域內的曲線一般不繪出或由實測得到。繪環電子的HUT-3X0系列超聲波探傷儀對A<3區域內的曲線進行了編程存儲于儀器內部，用戶只需要設置好探頭的相關參數就可直接調用。常州便攜式數字超聲波檢測儀廠家價格HUT-3X0系列手持數字超聲波探傷儀參考試塊的用途。
