| Abstract: | D welding temperature fields under a periodically welding heat source aresolved with BEM in Fourier transformed space. With the aid of the local effect principle,thecalculations are greatly reduced in relation to the fast Fourier transforms,which makes itpossible for the engineering application of the procedure proposed in the paper. |
