Visual inspection is a common method of quality control, data acquisition, and data analysis.Visual Inspection, used in maintenance of facilities, mean inspection of equipment and structures using either or all of raw human senses such as vision, hearing, touch and smell and/or any non-specialized inspection equipment.
Remote Visual Inspection or Remote Digital Video Inspection, also known as RVI or RDVI, is a form of visual inspection which uses visual aids including video technology to allow an inspector to look at objects and materials from a distance because the objects are inaccessible or are in dangerous environments.

Evidence-based practice is the idea that occupational practices ought to be based on scientific evidence.The movement towards evidence-based practices attempts to encourage and, in some instances, require professionals and other decision-makers to pay more attention to evidence to inform their decision-making.
Within a decade, the State of Connecticut passes a law requiring annual inspection (in this case visual) of boilers. 1880–1920 – The "Oil and Whiting" method of crack detection [11] is used in the railroad industry to find cracks in heavy steel parts. (A part is soaked in thinned oil, then painted with a white coating that dries to a powder.
Weld mapping is the process of assigning information to a weld repair or joint to enable easy identification of weld processes, production (welders, their qualifications, date welded), quality (visual inspection, NDT, standards and specifications) and traceability (tracking weld joints and welded castings, the origin of weld materials).
The Washington, D.C. Fire Department [17] was investigated for cheating on the NREMT certification exam; [18] however, an extensive investigation [19] by the NREMT and Pearson VUE, with assistance from the DC Fire and EMS department [20] as well as the DC police, revealed no evidence of cheating at Pearson VUE's LaPlata, MD testing center.
Accelerates structural steel erection by using shop-welded and field-bolted steel panels, and thus, less inspection and reduced quality control costs; Permits efficient design of lateral-resisting systems by distributing large forces evenly. A steel plate shear element consists of steel infill plates bounded by a column-beam system.
Magnetic flux leakage (TFI or Transverse Field Inspection technology) is a magnetic method of nondestructive testing to detect corrosion and pitting in steel structures, for instance: pipelines and storage tanks. The basic principle is that the magnetic field "leaks" from the steel at areas where there is corrosion or missing metal.
