Hello Dears,

Id like to have some opinions about the itens below:

CJP (complete joint penetration). A joint root condition in a groove weld in which weld metal extends through the joint thickness.

CJP groove weld (statically and cyclically loaded structures). A groove weld which has been made from both sides or from one side on a backing having CJP and fusion of weld and base metal throughout the depth of the joint.

CJP groove weld (tubular structures). A groove weld having CJP and fusion of weld and base metal throughout the depth of the joint or as detailed in Figures 2.21, 4.26, 3.6 through 3.10. A CJP tubular groove weld made from one side only, without backing, is allowed where the size or configuration.

My question is, if do you make a groove weld from one side only, without backing in statically and cyclically loaded structures, is there a PJP or a CJP?

Thank you very much.
