Finite Element Analysis (FEA) is used to investigate reasons why ASME VIII-1, FIG.UW-13.2, does not permit certain joint configurations for the attachment of welded unstayed flat heads:
- Joint Orientation: The eccentrically attached weld allows the joint to open under pressure.
- Fatigue Life: The peak stress created at the weld root limits the fatigue life.
- Weld size: The weld size is insufficient to satisfy the Code’s geometric requirements
