On the fracture behavior of the heterogeneous welded joint

This paper presents investigation of flaw influence, primarily in form of crack, on the fracture behavior of the heterogeneous welded joint. Investigation was done on butt welded I joint subjected to bending. This welded joint was repaired and in repair welding process additional weld material is implemented in weld producing heterogeneous welded joint with two weld materials and one base material. Since structural assessment procedures, like European Stuctural INTegrity Assessment Procedure (SINTAP), require determination of yield load of structure, fracture resistance of weld in this investigation was presented in context of yield load. All yield load solutions are obtained numerically, using finite element method, and compared to yield loads of the same construction but made of homogeneous material.
