Book Description
1 Scope This part of GB/T 3323 specifies techniques of radiographic examination of fusion welded joints of metallic materials. This part is applicable to the radiographic examination of welded joints of plates and pipes or other welded joints. This part does not specify acceptance levels for radiographic examination of welded joints of metallic materials. If contracting parties apply lower test criteria, it is possible that the quality of tested image is declined significantly. Note: This part meets the requirements of GB/T 19943, and the detector used is film. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Book Description
This document specifies the requirements for X-ray digital testing techniques of the longitudinal weld seam or helical weld seam of automatic fusion arc-welded steel tubes for the detection of imperfections, including the radiographic testing of computed radiography (CR) or digital detector arrays (DDAs). This document also specifies the acceptance levels and calibration procedures of digital radiographic testing. This document also applies to the testing of circular hollow sections.

Book Description
This document specifies the requirements for automated ultrasonic transverse wave (generated by conventional or phased array technology) inspection of submerged arc welded (SAW) steel tube or resistance and induction welded (EW) steel tube welds. For SAW tube, this inspection includes detection of imperfections primarily parallel to the weld, or perpendicular to the weld according to agreement, or in both directions. For EW steel tubes, this inspection includes the detection of imperfections oriented mainly parallel to the weld. For longitudinal imperfections, Lamb wave detection is chosen by the manufacturer. For imperfections in the EW tube welds, full circumferential ultrasonic inspection can be performed. This document also applies to the inspection of circular hollow profiles. NOTE: For full circumferential ultrasonic testing of seamless steel tubes and welded steel tubes (except SAW steel tubes), see ISO 10893-10.

Book Description
This Document specifies the general requirements and testing methods for ultrasonic testing of steel castings for general purposes. This Document applies to the ultrasonic testing of general-purposed steel castings having a grain refining heat treatment and a wall thickness not exceeding 600 mm. For steel castings with a wall thickness greater than 600mm, if there is no special requirement, refer to it. This Document does not apply to austenitic steel and austenitic-ferritic duplex stainless steel. Martensitic stainless steel can be implemented as a reference.

Book Description
This document specifies the requirements for automatic ultrasonic detection of laminar imperfection in steel strips/plates used for the manufacture of welded steel tubes before or during the tube making process. NOTE 1: For welded steel tubes, at the option of the manufacturer, automated ultrasonic testing of the steel tube for laminar imperfection according to ISO 10893-8 after welding is an alternative method. NOTE 2: Upon agreement between the manufacturer and the purchaser, this document is also applicable to the inspection of steel strips/plates after welding of submerged arc welded steel tubes. This document also applies to the inspection of steel strips/plates used in the manufacture of circular hollow steel profiles.
