ISO 10893-11:2011规定了埋弧焊(SAW)或电阻和感应焊(EW)钢管焊缝的自动超声波横波(通过传统或相控阵技术产生)检测要求。
对于埋弧焊管,该试验包括检测主要平行于焊缝或(经同意)垂直于焊缝或两者的缺陷。
对于电子战管,该试验包括检测主要平行于焊缝的缺陷。在纵向缺陷试验的情况下,制造商可自行决定采用兰姆波试验。
ISO 10893-11:2011也适用于圆形空心型材的试验。
ISO 10893-11:2011 specifies requirements for the automated ultrasonic shear wave (generated by conventional or phased array technique) testing of the weld seam of submerged arc-welded (SAW) or electric resistance and induction-welded (EW) steel tubes.
For SAW tubes, the test covers the detection of imperfections oriented predominantly parallel to or, by agreement, perpendicular to the weld seam or both.
For EW tubes, the test covers the detection of imperfections oriented predominantly parallel to the weld seam. In the case of testing on longitudinal imperfections, Lamb wave testing can be applied at the discretion of the manufacturer.
ISO 10893-11:2011 can also be applicable to the testing of circular hollow sections.
