| Popis: | 98 The distribution of welding residual stresses in high strength titanium bearing low carbon steel with two different initial plate temperatures before welding was measured and calculated under the same heat input. The as-welded 7 oC plate exhibited a higher residual tensile stress than as-welded 25 oC plate due to the greater temperature gradient. Diamond like carbon (DLC) thin film deposited on the as welded plates can reduce the magnitude of the welding residual stress caused by the cathodic arc physical vapour deposition (PVD) process. The distribution of the measured welding residual stresses agrees with finite element method (FEM) simulated results very well. |
