(a) The longitudinal profiles of specimens A5 and A6 on plane D, superimposed upon the metallography of the weld start and stop ends. The fusion boundary on plane D is inferred from the metallography. The green dashed line is the suggested fusion boundary from the metallography available. (b) The SCANSS model superimposed on the laser-scanned profiles and the inferred fusion boundary to locate measurement points on line D2. |
