After the process, grind the gouged surfaces to 1/16-inch (2 mm) extent. Grinding welds does inherently does lead to a reduction in the strength of the weld. However, the slip-on orifice flange is only available as a 300# raised face flange. If the weld is not filled flush to the HSS face (which is the situation shown in Figure 2), these effective throat sizes in Table 1 are reduced by subtracting the “underfill” dimension, which is the distance from the weld face to the HSS face (D f), as shown diagrammatically in Figure 2(c) and (d), to obtain the effective throat, E.
