The influence of the specific rehabilitation techniques „toegrindig” and „WIG remelting” in case of welded structure

Abstract

The fillet welded structures, fatigue stressed, must have a concave shape in cross section and a smooth transition between weldseamand base material, without stress concentrators . In this issue for the welded structures with convex fillet welds, to improve the behavior in case of fatigue loads it will be necessary to apply rehabilitation techniques like toe grinding or WIG remelting. The paper wants to present the influence of that two rehabilitation technique and the behavior of the rehabilitated welded structures in case of static and dynamic loads.
