Re: [MW:12164] relation between preheat or post heating to tensile strength

I would like to add few points to Mr.Kalyans Replay.

 

If the material being welded is Carbon steel you may not have higher affect on the metallurgical properties but, during SAW process you will get centerline crack if the width to height ratio of the weld bead is more than 2.

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?
