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 ... WebIn the case of the CJP and PJP welded connections, the flanges of the wide-flange beam are welded directly to the face of the HSS column. This often requires a thicker HSS wall than would be necessary for a cut-out plate or through-plate connection. Even taking into account the increased wall thickness, a direct PJP weld is by far the most ...
