The welding industry

In the welding industry, local heating often results in non-uniform temperature distribution, leading to structural thermal stresses that surpass material yield. These stresses can lead to fatigue or geometric distortions in the final design, affecting the equipment's operational life.

Key Highlights:

• Thermal & Mechanical Simulation: Using a two-staged coupled approach, we first compute the temperature history during welding and cooling, then apply this data to a mechanical model for stress analysis.

• Non-Linear FEA: Residual stresses are calculated using a non-linear FEA, revealing tensile stresses at ambient temperature close to the material yield (around 400 MPa).
• Ratcheting Protection: Our elastic-plastic analysis, compliant with ASME BPVC.VIII.2-2017 standards, ensures no permanent deformation due to thermal loads after three thermal cycles.

Understanding these residual stresses is crucial, as they can lead to brittle cracks under tension. Although thermal or mechanical relief methods can reduce these stresses, post-weld treatments are not always performed.

Our advanced FEA approach helps foresee potential issues, ensuring better structural performance and longevity for welded components. For a detailed explanation, check out the full article by clicking the link below. Feel free to contact us for more information!??
