Abstract
This paper deals with a tendon force, which was proposed by White, generating in welded joint by welding. Tendon force is an integral value of inherent stress which is equal to a restraint stress produced by an inherent strain. The inherent strain is connected with the maximum of temperature rise induced by an arc energy. Equations for the maximum temperature rise are classified by the non-dimensional welding speed parameter composed with a welding speed, a plate thickness and a thermal diffusivity. Predictive equations of the tendon force are proposed on the basic of inherent strain. It is shown that predictive equations are useful by comparing with experimental data.
