What is Vt weld inspection?
Prior to welding, the visual welding inspector checks the material for quality, type, size, cleanliness, flatness, straight line and dimensional accuracy then when the joint is prepared for welding it can be checked for alignment, fit up and correct joint preparation.
What is the most commonly used method of weld inspection?
Radiographic and ultrasonic weld inspection are the two most common methods of NDT used to detect discontinuities within the internal structure of welds. The obvious advantage of both methods is their ability to help establish the weld’s internal integrity without destroying the welded component.
Is special inspection required by the IBC?
Practically all engineered building projects require special inspections save those exceptions listed in section 1704.2 of IBC: Special inspections are not required for conventional residential light-frame construction (wood or cold-formed steel).
