Groove Welds

GROOVE WELD

The eight types of groove welds are shown by symbols that indicate how the members are to be prepared and welded, Figure 13.1. In the J - and bevel groove welds, only one of the two members is chamfered or beveled. To indicate the member to be prepared for these welds, the arrow breaks toward that member, Figure 13.2(a) and Figure 13.2(b).

The weld symbol is placed on the reference line in accordance with the usual arrow side, other side significance.

DEPTH OF GROOVE PREPARATION

The dimension for the depth of the groove is placed to the immediate left of the weld symbol, and on the same side of the reference line as the symbol.

In Figure 13.3(a), a V-groove weld is shown without a dimension. Therefore, the size or depth of the weld is assumed to be equal to the thickness of the pieces.
