Guide method for welded joint metrology - has measuring instrument to scan the weld bead materials and check accuracy of plate alignment

摘要

The measuring element of elements (1) are arranged movably on both sides of the weld seam both in relation to the basic material (3, 4) and in relation to the bead edge (2). On both sides along the weld bead both the distance ratios of the basic material and of the bead edge are measured, and the centre of the weld joint in the relevant measuring range is determined from the results of these measurements. The measuring element (1) can be movable, oscillating continuously, at right angles to the weld zone, from the area of basic material on one side of the weld zone to that on the other side of the weld zone.
