for many years the use of high strength steels in consturction 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 steels 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 pathc shapes.<\div>
