An analytical solution is computed for the thermal field induced in a semi‐infinite body by a moving heat source whose shape was proposed by Goldak et al. for the simulation of welding processes. Owing to its ability to accommodate a wide variety of welding techniques, this model is widely used. Throughout two semi‐ellipsoidal volumes, corresponding to the front and the rear parts of the moving source, the heat power density is distributed using a Gaussian function.
