Measurement of the height of :
-root height layer
-tact weld imperfection
Root height layer - the amount of penetration of the base metal when welding the root layer of a multi-pass seam.
Tact weld imperfection - the amount of penetration of the base metal when welding the root layer of a multi-pass seam. The height of the root layer of the seam and the requirements for its quality should be regulated according to the production and technological documentations
positioning the welding gauge
- Position the welding gauge on the surface of the base metal at a minimum distance from the measuring point.
- For greater of the welding gauge when taking measurements, use the pivots.
˟ красным цветом выделен параметр, подлежащий измерению
measurement taking
- Adjust the linear member 3 so that the taper gauge 5 is above the point of measurement.
- From the vertical scale H, take the readings of parameter h.
- To obtain the desired parameter s, measure the difference between the nominal thickness and the measured parameter.
