Abstract The hydrogen distribution in the welded joints and U-bend samples has been measured using the Laser Hydrogen Detector. WELDED JOINTS: 1. The highest hydrogen concentration is found along the fusion line. 2. The hydrogen distribution and content in welded joint depends on the original hydrogen content and the micro-structure of the welding metal and base metal. U-BEND SAMPLES: 1. In the plastic deformation region, the dislocation sets in motion of the hydrogen and the hydrogen is concentrated from the low-density region to the highdensity region of the dislocation. 2. The strain and residual stress has been calculated by means of the plastic mechanical nth-power law, shown as following: For the stainless steel 1Cr18Ni9Ti (cold rolled) F = 990 (MPa), n = 0.146.
