多通道新型鋼板探傷設(shè)備的改造與應(yīng)用

Modification of New Type Multi-channel NDT system for Steel Plate Inspection and Relevant Application

摘要: 通過分析焊縫兩側(cè)母材的夾雜物和分層缺陷，提出了一種對(duì)多通道新型鋼板探傷設(shè)備進(jìn)行改造的方案，包括增加組合探頭以及對(duì)探頭的合理排列布置。改造后，12組斜探頭和兩組四合一組合探頭，分別對(duì)鋼板板邊一定范圍進(jìn)行100%橫波、100%縱波探傷，顯著提高了鋼板缺陷的檢出率。

Abstract: A plan is proposed for modification of the new type multi-channel NDT system for steel plate inspection, based on the analysis of the inclusions and lamination defect as existing in the base metal on both sides of the weld seam, including measures like adding integrated probes and properly re-arranging the probe array, etc.After the modification, the detection rate of the system has been remarkably enhanced, owing to the twelve groups of oblique probes that are capable of 100%coverage transversal wave detection to certain area of the steel plate edge, and the two sets of the four-in-one integrated probes that are capable of 100%coverage longitudinal wave detection to the same area of the steel plate.
