| Abstract: | Starting from the basic differential equation of solid heat transfer, the 3-D boundary integral equations are developed for two problems of welding heat transfer under constant: heat source and periodic heat source, together with the proposal of special treatment of their boundary conditions, which lay a foundation for the boundary element analysis of quasi-steady heat transfer problems of welding. |
