PROFILED PIECE MADE OF CERAMIC FOR THE FORMATION OF SECURING SUPPORTS FOR MOLTEN WELD POOLS FOR WELDING

摘要

The invention relates to a profiled piece (1) made of ceramic for the formation of securing supports for molten weld pools, in particular for arc welding, wherein a number of profiled pieces (1) can be laid next to each other with the front side (2) of one profiled piece next to the back side (3) of a preceding profiled piece (1) of the same design, and wherein each profiled piece (1) has an upper side (4) and a lower side (5) which are connected to each other by means of the side edges (6 and 7) and by the front sides (2) and the back sides (3), wherein the front side (2) and the back side (3) are spherical surfaces with the same radius, and wherein the spherical surface on the front side (2) of the profiled piece (1) is a convex curve and, on the back side (3), a concave curve. The centers of curvature (M1, M2) of both the front side (2) and the back side (3) are arranged above the center plane of the profiled piece (1).
