Weld-on Padeyes

[Dnki]

I understand that a weld-on padeye is difficult to rate. Is there an easy way to find the right padeye for my application and subsequently rate said padeye once it has been attatched?

A) Load test.
B) Letter from a PE with calculations.
C) Combination of A) and B)

Expanding on zcp's suggestions:

A) Understand the application and the nature and magnitude of the loads.

B) Determine an appropriate safety factor.

C) Select a weld joint capable of sustaining A x B.

D) Design a weld procedure capable of consitently producing the weld selected in step C.

E) Qualify the weld procedure by load test of the assembly, and some combination of weld sectioning, radiographic, ultrasonic, DP or MP testing.

F) Qualify as many welders as you need for that procedure.

Analysis or actual max working stresses must be determined based upon working conditions including impact or other factors pertinent to the application. Actual max working stress must be equal to or less than the allowable stress.

I would consider using ASME B30.20a-2001 Structural and Mechanical Lifting devices as a start:
