The 'weld quality' in structural steel is inspected by:
Choose the correct answer
Only visual inspection is allowed
Visual + RT (X-ray) for butt welds, UT for thick welds, MPI/DP for surface defects — IS 822 governs inspection
Only by cutting the member apart
Hardness test only
Correct Answer
B. Visual + RT (X-ray) for butt welds, UT for thick welds, MPI/DP for surface defects — IS 822 governs inspection

Weld inspection methods: (1) Visual inspection (all welds — IS 822); (2) Radiographic testing (RT — X-ray or gamma ray, for butt welds — ASME/AWS D1.1); (3) Ultrasonic testing (UT — cleaner, no radiation, good for thick welds); (4) Magnetic particle testing (MPI — surface/near-surface defects in ferromagnetic materials); (5) Dye penetrant (DP — surface cracks). IS 814/IS 816 weld quality requirements.
