The material properties are related to the mechanical and acoustic properties of anisotropy. These characteristics are distinct from the isotropic characteristics of low-alloy steel welds. Compared. Austenitic welds and other coarse-grained anisotropic materials significantly affect ultrasonic propagation. In addition, fusion lines and/or columnar crystals may produce Acoustic beam distortion, abnormal reflection and wave form conversion. Therefore, it is difficult for ultrasonic to penetrate the weld metal, and sometimes it cannot penetrate the weld metal. This type of metal ultrasonic detection technology is different from conventional ultrasonic detection technology. This type of detection technology usually does not use conventional shear wave oblique probes, and Use oblique incident longitudinal wave dual crystal probe or creeping wave probe. In addition, it is necessary to make a typical reference test block with welds so as to study the inspection process and set the initial Start sensitivity level, evaluate and confirm the effectiveness of the testing process. Refer to the characteristics of the material, groove, welding process, size and surface condition of the test block The point is consistent with the inspected part. Ultrasonic testing for non-destructive testing of welds Austenitic steel and nickel-based alloy weld inspection1 ScopeThis document specifies the principles to be followed when formulating the following procedures for ultrasonic testing of test objects. ---Stainless steel welds; ---Nickel-based alloy welds; ---Dual-phase steel welds; ---Dissimilar metal welds; ---Austenitic steel welds. The purpose of the test may vary, for example. ---Quality grade evaluation in manufacturing. ---Detection of specific discontinuities in service. This document does not contain the acceptance level, but the acceptance level can be determined according to the detection range (see 4.1). This document is suitable for manual inspection and automatic inspection.2 Normative referencesThe contents of the following documents constitute the indispensable clauses of the text through the normative references in the text.
