Abstract: | Die Sichtprüfung von Schweißnähten ist die einfachste und am häufigsten durchgeführte Art der Schweißnahtprüfung. Neben laufenden Soll-Kontrollen durch das Schweißpersonal während der Fertigung ist für alle Ausführungsklassen abschließend eine vollumfängliche Sichtprüfung nach EN 1990-2 [1] durchzuführen. Dabei können direkte und indirekte Prüfmethoden angewendet werden, zu denen auch die Geometrieerfassung durch Laserscanning zu zählen ist. In diesem zweiten Teil des Beitrages wird die Anwendung eines mobilen Laserscansystems für den klassifizierenden Vergleich zur rein rechnerischen Ermittlung der Ermüdungsfestigkeit erläutert (Teil 1 s. Stahlbau, H. 5, S. 336-343). Assessment of welds based on 3D laser scanning. Practical application of a mobile laser scan system for the surface assessment of welds - Part 2. The visual examination of welds is a simple and frequently used method for weld inspections. Besides the comparison between a target and performance state executed by the technical staff during the production process, a final visual inspection of the welds for all execution classes is demanded by EN 1990-2 [1]. According to this standard, direct or indirect methods can be applied. An example for an indirect method is the scanning of the real geometry of the weld using laser scan technology. In this second part of this article the application of a mobile laser scan system is used as a base to quantify and compare the fatigue limits of scanned specimens with numerical methods only. |
