What's the meaning for (A.6) any other linear indications greater than 3⁄16in.(5.0 mm) long.
Somebody knows what is exactly "any other linear indications" for visual examination?

By definition cracks are linear. Undercut, slag inclusions, elongated porosity, incomplete fusion, and overlap are a few additional examples of weld discontinuities that are typically linear. In general the severity of a discontinuity is influenced by: the location, i.e., surfaces versus subsurface, nature of load conditions, i.e., static versuis cyclic, end conditions, i.e., rounded versus sharp, linear versus nonlinear, and whether the dscontinuity is subject to tension or compression.
