| TABLE J2.5 Available Strength of Welded Joints, ksi (MPa) | |||||
|---|---|---|---|---|---|
| Load Type and Direction Relative to Weld Axis | Pertinent Metal | Φ and Ω | Nominal Stress, FnBM or FnW, ksi (MPa) | Effective Area, ABM or Awe, in.2 (mm2) | Required Filler Metal Strength Level[a][b] |
| COMPLETE-JOINT-PENETRATION GROOVE WELDS | |||||
| Tension— normal to weld axis | Strength of the joint is controlled by the base metal. | Matching filler metal shall be used. For T- and corner-joints with backing left in place, notch tough filler metal is required. See Section J2.6. | |||
| Compression— normal to weld axis | Strength of the joint is controlled by the base metal. | Filler metal with a strength level equal to or one strength level less than matching filler metal is permitted. | |||
| Tension or compression— parallel to weld axis | Tension or compression in parts joined parallel to a weld is permitted to be neglected in design of welds joining the parts. | Filler metal with a strength level equal to or less than matching filler metal is permitted. | |||
| Shear | Strength of the joint is controlled by the base metal. | Matching filler metal shall be used.[c] | |||
| PARTIAL-JOINT-PENETRATION GROOVE WELDS INCLUDING FLARE-V-GROOVE AND FLARE-BEVEL-GROOVE WELDS | |||||
| Tension— normal to weld axis | Base | Φ = 0.75 Ω = 2.00 | Fu | See J4 | Filler metal with a strength level equal to or less than matching filler metal is permitted. |
| Weld | Φ = 0.80 Ω = 1.88 | 0.60FEXX | See J2.1a | ||
| Compression— connections of members designed to bear as described in Section J1.4(b) | Compressive stress is permitted to be neglected in design of welds joining the parts. | ||||
| Compression— connections not designed to bear | Base | Φ = 0.90 Ω = 1.67 | Fy | See J4 | |
| Weld | Φ = 0.80 Ω = 1.88 | 0.90FEXX | See J2.1a | ||
| Tension or compression— parallel to weld axis | Tension or compression in parts joined parallel to a weld is permitted to be neglected in design of welds joining the parts. | ||||
| Shear | Base | Governed by J4 | |||
| Weld | Φ = 0.75 Ω = 2.00 | 0.60FEXX | See J2.1a | ||
