Product Overview:

Fusion welding has played a critical role in shaping modern civilization, serving as a fundamental technique in construction and manufacturing. Aside from bolts and rivets, fusion welding is one of the most reliable methods for securely joining metal components. It is commonly used in the production of various essential items, including airplanes, automobiles, and large-scale structures. Additionally, fusion welding, particularly arc and flame welding, is widely utilized in the art community to create metal sculptures.

In this simulation, the fusion welding process is modeled, with a focus on investigating residual stress using the DFLUX subroutine in Abaqus. The DFLUX subroutine is applied to simulate non-uniform heat distribution along a circular path on a steel pipe. As the heat moves during the process, residual stresses are generated.

Key Topics:

• Creating and defining the geometry of the welding setup.
• Customizing material properties for accurate temperature-dependent analyses.
• Setting up simulation steps to evaluate stress distribution post-welding.
