Development of a physical simulation method of steel welds for fatigue crack propagation studies, on heat affected zones
In order to study the fatigue crack propagation in the Highly Affected Zone (HAZ) of structural steel weld joints, test specimens of 90 mm x 49.5 mm x 7 mm in size were used to carry out the simulations, for which a special procedure was required to be developed in the Gleeble system.

| description | In order to study the fatigue crack propagation in the Highly Affected Zone (HAZ) of structural steel weld joints, test specimens of 90 mm x 49.5 mm x 7 mm in size were used to carry out the simulations, for which a special procedure was required to be developed in the Gleeble system. By doing so, the fine grain zone, the coarse grain zone and the multi-pass zone of a weld joint were successfully reproduced separately, on different samples of the corresponding base metal, produced by FCAW. The simulated zones were reproducible, homogeneous, defect-free, residual-stress-free and large enough, besides their microstructural characteristics (such as grain size and phase percentage) were very close to their real counterparts, which made it possible to study the actual effect of HAZ microstructure on the fatigue crack propagation rate in these zones for the first time. Therefore, the development enabled to significantly applications and the advantages increase, that this technique may have, while allowing to improve the understanding of fatigue behavior in steel weld joints. |

Therefore, the development enabled to significantly applications and the advantages increase, that this technique may have, while allowing to improve the understanding of fatigue behavior in steel weld joints. Se presenta el desarrollo de un método de simulación física, a través del sistema Gleeble, de las zonas térmicamente afectadas de uniones soldadas de aceros estructurales (A283 Gr. C y A106 Gr. B), para el estudio de la propagación de grietas por fatiga. Para ello fue necesario utilizar probetas de 90 mm de largo, 49,5 mm de ancho y 7 mm de espesor, en una configuración que no se encuentra dentro de los estándares del sistema para este tipo de simulaciones. Con este método se reprodujeron satisfactoriamente, y por separado, en diferentes probetas del metal base correspondiente, la zona de grano fino, la zona de grano grueso y una zona de múltiples pasadas presentes en uniones soldadas fabricadas por FCAW. Las zonas simuladas fueron reproducibles, homogéneas, no presentaron defectos ni tensiones residuales y tuvieron un tamaño considerablemente grande, además que las características microestructurales (como el tamaño de grano y el porcentaje de fases) fueron muy similares a su contraparte real, lo que permitió estudiar por primera vez el efecto neto de la microestructura sobre el comportamiento a la fatiga en estas zonas. De esta manera, el desarrollo realizado permitió aumentar considerablemente las aplicaciones y las ventajas que esta técnica puede tener, además de mejorar la comprensión del comportamiento a la fatiga de las soldaduras de acero.
