In it we will show the AWI analysis methodology provides reasonably accurate predictions of resulting temperature history and residual stresses, with significant savings in construction of complex 3-D weld models. characteristics are studied based on which laser welding process is selected.

Check out the full tech brief to learn how AWI is used to model multi-pass welding of an SUS304 stainless steel pipe joint. This translates into cost advantage by saving on prototyping and experiments, while also reducing costly in-service failures.

The Abaqus Welding Interface or AWI is an extension of Abaqus/CAE that is well-suited to help predict welding residual stresses during the design process of pipe joints. It is important to accurately determine the integrity of piping system in order to reduce the possibility of failures. Pipes are an integral part of everyday happenings in many businesses across an array of industries. When the general contact algorithm is used, Abaqus also provides a default all-inclusive, automatically defined surface that includes all element-based surface facets (in Abaqus/Standard and in Abaqus/Explicit), all crack surfaces for enriched elements (in Abaqus/Standard only), all analytical rigid surfaces (in Abaqus/Explicit only), and all. The modeling was performed using the software ABAQUS. Analysis of vibration-induced fatigue cracking in steel bridges Master’s Thesis in the Structural Engineering and Building Performance design.
