| Summary: | The built-up welding technology is a specialized process, which has many applications in welding industry. A single electrode submerged arc welding is applied to deposit a thick weld metal layer on a dummy low carbon steel plate for shaping a bulk component, which is approximately all weld metal. Failure occurs rarely in service, and initiates at a notch like defect. Present work aims at evaluating the effect of notch geometry with different sharpness at different loading rates on the tensile properties of steel weld formed built-up multi layers component using the submerged arc welding. In addition, the behaviour of such a component during room temperature impact loading at different notch orientations is evaluated. Besides, weld homogeneity is studied through hardness measurements. The results indicate that, steel weld formed built-up multi layers component is sensitive in tensile loading to both high loading rates, and the presence of sharp notches (like defects), and insensitive to the orientation of notches under room temperature impact loading. Moreover, isotropy of weld structure is indicated through the regularity of hardness measurements. |
