ABSTRACT:
The ribbed article has ribs which are built-up of multi-layer ribs. In the crossing points or overlap zones, some of the weld seams of one rib are continuous or discontinuous while the weld seams of the crossing rib are discontinuous or continuous as the case may be. The overall height of the overlap zone is the same as the ribs forming the overlap zone. A pair of guide beads are also applied to the base member prior to application of the first weld layer of a rib in order to guide the build-up of a rib.
