Welding Visual. The most common welding discontinuities found during visual inspection are conditions such as undersized welds undercut overlap surface cracking surface porosity under fill incomplete root penetration excessive root penetration burn through and excessive reinforcement. May assume the lack of continuous weld inspections can be easily solved by having an inspector come out and do a visual inspection for all completed weldmentss.
Welders operators line inspectors and foremen who undertake visual examination of welded joints. Visual-weld-inspection is intended to find and mark for repair obvious visual nonconformances such as cracks surface porosity dimensional discrepancies excess concavity or convexity unfilled areas undercut misalignment craters unacceptable arc striking spots and any other objectionable visual features. Dimensional and visual checks of the weld dont identify welding discontinuities excessive distortion and poor workmanship.
Main responsibilities of a welding inspector are.

Visual inspection is limited to detection of surface discontinuities. T is the thicknesses of the weld which is excluding any allowable reinforcements.
