VT - Vusual Measurement control

This is one method of nondestructive testing of the optical appearance. It is based on the receipt of the initial information about the controlled object by visual inspection or by using optical devices and measuring instruments. This organoleptic control, ie, perceived by the senses (of bodies) GOST 23479-79 "Non-destructive testing. Methods of optical species "establishes requirements for methods of controlling the optical appearance.

By inspection (VIC-ohm) check the quality of the preparation and assembly of workpieces for welding, quality of welds during the welding process and the quality of the finished welded joints. As a rule, by inspection control all welded products, irrespective of whether other types of control. Visual control in many cases quite informative and is the cheapest and most expeditious method of control.

Visual inspection method can detect discontinuities, deviations in size and shape from the set of more than 0.1 mm when using devices with an increase of up to 10 x.

Visual inspection is generally performed by the naked eye or using a magnifying loupe to 7 x. In doubtful cases and technical diagnosis is allowed to use loops with an increase of up to 20 x.

Before performing visual inspection of the surface in the control zone must be free of rust, scale, dirt, paint, oil, spatter, and other contaminants that hinder inspection.

When Visual and measuring control welds zone control is weld and adjacent portions of the base metal at a width of not less than 20 mm to each side of the seam with two surfaces, if both of these are available for inspection.

Visual inspection is performed prior to other control methods. Defects detected by visual inspection, should be removed prior to control by other methods.

Measurements are made using instruments and tools:

Measurements are made using instruments and tools: 

 

  • Measuring magnifier;
  • Calipers;
  • A ruler measuring metal;
  • Inclinometers;
  • Squares;
  • Probes;
  • Templates and others.
