WebInstead, point the weld arrow to the joint location and call out CJP or PJP as shown in the following figures. The welding symbol for CJP weld does not denote weld size: Figure 11.3.1 CJP Welding Symbol . The welding symbol for PJP weld denotes effective weld size (E1) for other side and (E2) for arrow side: Figure 11.3.2 PJP Welding Symbol WebA complete weld penetration, or a full weld penetration, is the most effective technique for producing a thick weld. Weld passes may be used to bevel and penetrate the weld. In joints with thicknesses of 0.20 inches or more, you can still obtain penetration without creating a groove bevel. The partial penetration welds are not as thick as the ...
