Stainless steel metallurgy for welding

[@johnhenryutley]

Hi Girish, this is Henry. Regarding the addition of 309 to the 304-mild steel weld, how do you come to the conclusion of what percentage of filler will be part of the fusion zone?

[@weldnugget]

Hi Henry, filler percentage depends on part geometry and size of weld. Square butt joints will have less filler and more base metal. A V-groove joint will have more filler and less base metal. To know for sure you will have to measure weld chemistry (EDS) on a weld section, and then use the Schaeffler diagram to plot it out and back calculate the percentage.
