Crack Propagation in welded joints in low alloy carbon steel under cyclic loading.
Sergio Antonio Muñoz Pinzón
The quality of welding is a repeated issue and one of the key parameters in assuring the integrity of a structure. Welds not only join two parts of a component together, they also provide a source of defects, and they provide a continuous path for the propagation of a crack throughout a component. Weld quality has the potential to be extremely variable, as good control is only obtained for factory welds and inevitably many welds have to be performed in site conditions.In pipelines, long sections of pipe are welded together on site, often in hostile conditions, making them more difficult to control. In long pipelines, there are many km of weld, and defect-free ones cannot be guaranteed.[1].
