This paper seeks to describe relationships between the independent process variables and the dependent process outcomes related to heat generation and dissipation in friction stir welding. A conceptual model, proposed earlier, has been modified to specifically distinguish between plastic work and friction in the generation of heat. A case study is used to confirm and explore the relationships expressed in the conceptual model. Further, a method for expressing friction coefficient variation with respect to the key process variables is introduced.
