Schweißnahtbewertung basierend auf 3D-Laserscanning - Praktische Anwendung eines mobilen Laserscansystems zur Oberflächenbewertung von Schweißnähten - Teil 2

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.
