Temper bead welding is usually done by experiment, i.e., trial and error. This paper describes a computational weld mechanics model to compute the transient temperature and transient microstructure evolution in temper bead welds. The computed hardness from this model, is compared to measured hardness for validation. Furthermore, the effects of power per unit length, welding current, and welding speed on final hardness, are studied by designing and implementing three design-of-experiment matrices.
