DNV OS-C101-WSD Weld Strength (2024)

DNV OS-C101-WSD Weld Strength (2024) provides a framework for assessing weld strength under service conditions using the Working Stress Design method. Implemented per Chapter 2, Section 5, this check includes:

• Weld throat stress calculations at both weld ends
• Eccentricity effects for single fillet welds
• Safety factor support via Eta₀w_a, Eta₀w_b (Table 5)
• Material-based factors like Beta_w and Gamma_M

Minimum weld leg length is validated using Table 2, with flagged results if geometry requirements aren’t met. All stress checks are performed in the weld coordinate system assuming a 0° angle.

Key weld properties and stress results are automatically generated using input geometry, enabling efficient and standards-compliant verification in offshore frames, tanks, and deck structures.
