Weld Static Strength Checklist
Review prompts for weld static strength — throat thickness, weld length, stress type and allowable source.
Purpose
For checking weld static strength assessment.
Geometry
- Is the weld throat thickness correctly defined? — Throat = 0.707 × leg for fillet
- Is the effective weld length correct — excluding start/stop craters? — Per standard
- Is the weld type identified — fillet, butt, partial penetration? — Different allowables
Stress
- Is the stress on the weld throat correctly calculated? — Shear on throat for fillet
- Is the correct allowable used — weld metal or parent metal? — Typically the lower
- Is the allowable from the applicable standard (BS EN, AWS, IIW)? — Not estimated
- Is combined shear and normal stress on the throat assessed? — Vector sum or interaction
