| Abstract |
The earlier method for reconstructing the welding thermal cycle from the dislocation of the temper colors and the cold weld joint boundaries was applied in the case of contact flash welding of rod samples. The possibility of using this method to determine the key parameters of the welding processes such as the approach speed of the welded rods, the temperature at the weld center at the beginning of cooling, and the time in which the characteristic temperature isotherm moves to the largest distance from the weld center, which allow one to reconstruct the temperature distribution curve near the weld at any time after the heating termination, was shown. The reconstructed thermal cycle was used to determine the residual stresses in the weld and in the heat-affected zone. |
