Welding is a commonly used method that plays a crucial role in the safety, structural integrity, and durability of many fabricated structures. If a weld fails due to different modes of failures (tension, compression, bending or torsional loads), the weld will no longer be able to transfer loads between the welded components. In some cases, this may lead to the collapse of the whole structure as the weld might play a role in transferring critical load.\u00a0 Therefore, when designing these welds, it is vitally important to account for loading requirements, the welding process, and fatigue among other factors to prevent structural failures. Due to the geometry and the weld itself being complex, the most typical way to analyses these welds are using finite element analysis (FEA). Ansys Mechanical 2022 R1 provides a number of significant new features which greatly aide the preparation of a welded FEA model – in our experience from working on many industrial projects involving complex welded structures, these new features and capabilities in Ansys 2022 R1 will significantly reduce the model preparation time – in many cases, from a week (or more) to 1-2 days (depending on geometric complexity).<\/p>

In the manufacturing process of seam welds, it is sometimes common to allow breather areas or intermittent welds. The mesh-based seam welding also supports intermittent seam welds where the user can add additional parameters to control the properties.\u00a0 Like with other seam welds, the user can specify if they simply want normal (extensions), angled (tents), or both. An example of intermittent seam weld is shown in Figure 1, from the input CAD to the meshed model.<\/p>

The creation of seam welds has become a lot easier in the latest release of Ansys Mechanical 2022 R1. Before we jump onto the new features, let\u2019s define some general terminologies surrounding seam welds. Figure 3 shows the features of a continuous seam weld and Figure 4 shows the features of an intermittent seam weld.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

There has been a significant improvement in the way you can visualise the weld once the solve is complete.\u00a0 Welds are now shown in blue, yellow, and red colours to help visually identify welds based on their status (blue = passing, yellow = warning, and red = failing status) as shown in Figure 6.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
