measurement of geometric parameters of a dent

Dent - surface defect, which occurs without violating the continuity of the metallic pipe due to impacts during transportation or trimming

  • Position the welding gauge on the surface of the base metal at a minimum distance from the measurement point. 
  • For greater stability of the welding gauge when taking measurements, use the pivots 

˟ красным цветом выделены параметры, подлежащие измерению

  • Lower the fillet arm 2 or the taper gauge 5 into the cavity of the dent until they come into contact with the deepest point on the surface of the dent. 
  • Take the value of the desired parameter h on the appropriate scale as shown. To measure the length and width of the dent, use the ruler L.
