I've been struggling with this calculation. How do I know the force "P" that the following welding can take? I have some formulas of shear such as shear stress in the throat section of the weld, but I can't relate it to the weld stress. I guess my question is which formula should I use for this calculation?

I have the throat area for this welding will be 0.707h(b+2d), where b and d are known dimensions (weld around metal piece), and h will be the welding thickness.
If T (shear stress in the throat section, parallel to the axis of the weld) equals to: P/(2xdxA), can I solve for P and give T the value of the maximum tensile strength of the welding?

Thanks.
