Abstract

For many years, the use of high strength steels in construction is increasing due to high ratio of strength to weight and cost considerations. These properties reduce the fabrication cost and time. To make use of these advantages of these modern steels, their weldability was extensively evaluated. In the present study a dissimilar patch welds between two high strength steels was investigated. A series of dissimilar steel joints based on the S600MC (as the base plate) and S355 (as the patch plate) were produced using robotic MIG welding. Residual stresses were determined using the X-ray diffraction (XRD).The effect of welding speed and sequence on residual stresses distribution in two different patch shapes was studied. Analysis of the results revealed that using of the welds in opposite directions reduces the welding stresses and the effect of welding speed is different in two patch shapes. It was found final state of residual stresses depends on all of theses parameters.
