The Influence of hte Composition of the Weld Metal on the Stress Fields around the Welds on the High-Sttrength Ferritic Steel Weldox 700

Original language description

The high-strength steels are developed in order to provide the favorable mechanical properties and higher corrosion resistance in relation to conventional carbon steel grades Weldox 700 is such a general structural steel with a minimum yield strength of 650 - 700 MPa. Typical applications are very demanding e.g. load-bearing, structures, pipes, bridges, steel structures storage tanks etc. which are very often composed of the welded parts. The quality of the welds depends besides other things on the residual stresses in the vicinity of the welds. Therefore, the influence of the weld metal chemical composition on residual stress distribution in the vicinity of test welds was studied. Butt welds were prepared in a high-strength steel using two basic shielded metal arc electrodes ─ one conventional producing a bainitic weld metal and one experimental low temperature transformation (LTT) electrode depositing a martensitic weld metal. Welding was done under restraint in a test frame. Residual stress components were measured across the weld using neutron diffraction after removing the test weld from the frame. It was found that the stresses were generally on a lower level for the LTT weld. The largest difference was seen for the transverse residual stress some distance into the heat affected zone.
