Height measurement of the incomplete filling and the crater depth 

Incomplete filling  - It’s a continuous or an intermittent longitudinal groove on the surface of the weld formed due to insufficient filler material

  • Set the welding gauge at the zero position  
  • Pull the fillet arm 2 out of the main gauge plate 1, matching the mark with a value corresponding to the diameter of the pipe being monitored 
  • Fix and lock the stop position by tightening the fillet arm rivet 6. 
  • Position the welding gauge on the test object. 
  • After rearranging the pivots in the groove located on the right side of the welding gauge, adjust them until they come into contact with the inspected object.
  • Lock the pivots in this position as shown by the illustration

˟ красным цветом выделены параметры, подлежащие измерению

  • Adjust the linear member 3 so that the taper gauge 5 is above the point of measurement (at the point of greatest concavity). 
  • Take the value of the parameter w on the horizontal scale W, and subsequently the readings of h from the vertical scale H
  • Lower the top High-Lo arm 4 so that the taper gauge 5 makes contact with the surface of the test object at the point of measurement. 

To determine the desired parameter h illustrated, use a calculator
