Welding calculation

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.

use shear strength instead of tensile where shear is normally 0.57 of the yield strenght (for most metal, could be different or specific for specific material). yes you can find what is P then.
