Boy, I wish I wasn't protesting.
Think linear versus nonlinear. Which is more detrimental to the weld? Also consider the location of the defect, surface breaking versus subsurface. Then consider where the highest fiber stresses are located, surface versus subsurface. Lastly, consider the NDE method; visual.
Weld profile takes into account those considerations when setting the limits of acceptance. The attributes called profile are a consideration when performing VT in accordance with Table 6.1.
