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
positioning the welding gauge
- 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

measurement taking
- 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.
