    CJP groove weld requirements for HSS-to-HSS T-, Y- and K-connections are given by AWS D1 1 Clause 10 10 and in the figures referenced For the end-plate example in Figure 1, a prequalified CJP welding procedure specification (WPS) for this T-joint can be obtained from Figure 5 1 of AWS D1 1 Clause 5, or Table 8-2 in the AISC Manual (AISC, 2023

    You need to qualify a new WPS Box tubing WPS qualification requires qualification to tubular connections the macro-etch samples and such as listed in AWS D1 1 if a T-Y-K connection is involved
  • AWS D1. 1 Guides-2025 - WPSAmerica
    Note 1: If PJP WPS not using any Figure 5 2 joint detail, (when CJP WPS would be supporting PJP), additional three macroetch test specimens are required to evaluate weld soundness and to verify that the required weld size is produced (weld parameters must be within those specified on CJP WPS)

Because Butt joint is not Fillet :)) Tensile, Root bend, Face bend, Side bend see Table 4 3 for more note on PJP T-corner joints rarely use ( backgouging will be cost very big sample!)
