210 Welding Print Reading For round parts, the first dimension is the radius of the round part. Figure 16-28 shows the round bar has a radius of 1.00 and a weld size of .75. If only one part is round or formed, then the formed part and a straight part form a flare-bevel-groove weld. Figure 16-30 shows a formed part welded to a straight part. The dimensions used to describe the flare-bevel- groove weld have the same meaning as those used for the flare-V-groove weld. The first dimension indi- cates the distance from the top of the part to the point of tangency and the second dimension indicates the size of the weld. Notice that the first dimension for round parts indicates the radius of the round part. See Figure 16-31. Combination Weld Symbols Combination weld symbols are used when other types of welds are required in addition to groove welds. Figure 16-32 shows a flare-bevel-groove weld with two fillet welds. The weld symbols specify a fil- let weld over the flare-bevel-groove weld on the arrow side, and a fillet weld on the other side. The dimensions for the combination symbol are applied in the same manner as those used for the flare-groove weld symbol and the fillet weld symbol. Figure 16-30.
