Web• Developed a welding procedure for ID weld overlay of the API 5L (PSL 2) grade pipe with CRA layer of SS316L and Inconel-625. • Performed NDTs & Evaluated mechanical, chemical & corrosion resistance properties of weld overlay. • Developed an Android based application for prediction of Bead height, Arcing time & Clad weight. WebFeb 15, 2005 · We've had problems with alloy 625 overlay on tubes where adjacent weld beads (longitudinal passes) are too close together when a final pass is made to close the gap between the two beads. You get lack of fusion at the tube/overlay interface and (in some cases) an axial crack running down the center-line of the final cap bead.
