Visual Welding Inspection
Visual Weding Inspection (VT)
Visual inspection is easy to apply, quick and requires only a few small items of equipment. IRISNDT has Visual Welding Inspectors qualified to CSWIP 3.0 level.
Visual inspection involves more than just inspecting the finished weld. The visual welding inspection process is performed prior, during and after welding.
Prior to welding the visual welding inspector can check 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. During welding the visual welding inspector can check the weld bead profile and inspect for any surface defects, this is especially useful when welding multi-pass welds as highlighting surface defects at this phase can save on weld repair costs at a later stage. After welding the visual welding inspector can check for a variety of surface flaws, such as; cracks, porosity, crater cracks, undercut, arc strikes, spatter and weld profile.
IRISNDT has inspection procedures in place for inspecting to BS EN 970 and ASME V, Article 9. The Technicians are experienced in visually inspecting welds to most recognised national standards such as NSSS and AWS D1.1, welds are measured and compared to the appropriate standard, any defects are noted, characterised and evaluated to the applicable standard and concise test reports are formulated to satisfy our clients demands.
