[MW:11989] relation between preheat or post heating to tensile strength

Dear experts,

                   Please solve my doubts

                   Could u please explain

                   1) Is their any relation between Preheating/ Post heating/interpass temp to Tensile strength?

                   2) metallurgically what will happen when bead width and bead thickness increases in SAW process? Is this any effect to tensile strength?
