... transformation characteristics of the steel and the cooling rate after the weld has solidified. This cooling rate varies with time and distance from the fusion front and is influenced by a number of welding parameters. For example, it decreases when the rate of heat input into the weld metal is increased, when...

... fatigue life can be obtained by reducing the effects of one or more of these parameters. This is particularly true for cracks starting from the weld toe, which is by far the most common failure site. In load-carrying fillet welds, however, cracks can start at the weld root and propagate through the weld...
