Welding Inspection Tools Hi-Lo Weld Gauge
Basic Info
Hi-Lo Welding Gage measures Internal Alignment of pipe after fit-up/alignment, cuts radiographic rejects. Will also measure internal misalignment of pipe before and after tacking. Measurements read in standard one side, metric opposite side. Plus six other critical, required measurements! side.
The Hi-Lo Welding Gauge is a multipurpose and versatile gauge. As with many of our gauges, both standard and metric units of measurement are available directly on the gauge for dimensional verification.
With the Hi-Lo Gauge, you can measure:
* Internal misalignment after fit-up
* Material thickness after fit-up
* Verify 37-1/2 degree bevel angle
* Fit-up gap after fit-up
* Fillet weld leg length
* Butt weld reinforcement
We'll start with an internal misalignment measurement.
First loosen the locking screw and insert the gauge tip into the fit-up gap.
Now rotate the gauge 90 degrees and slide the gauge body until it comes in contact with the outside diameter of the pipe. This verifies that the gauge is square and the reading is correct.
Next, pull down the gauge until the internal alignment stops are snug against the inside of the pipes.
Read the misalignment on this scale. This misalignment measures 3/32 of one inch.
You can use the same procedure to measure pipe wall thickness after fit-up.
To measure pipe wall thickness, use the material thickness indicator and this scale. This pipe measures 3/32 of one inch.
This gauge can also be used to verify a 37-1/2 degree bevel angle.
To check bevel angle, be sure to set the alignment scales to the zero position.
Now place the gauge body squarely against the pipe wall and push the gauge as far as it will go into the fit-up gap. If the beveled shoulders on the gauge fits snug against the bevel on the pipe end, you have the correct 37-1/2 degree bevel common to most pipe end preps.
To measure fit-up gaps less than 1/16 of an inch, insert the alignment stops into the fit-up gap. If the thinner portion of the gauge does not fit, then the gap is less than 1/16 of one inch. If it partially fits in the gap, then the gap is somewhere between 1/16 and 3/32 of one inch. Finally, if the stops go through the gap, then the gap is larger than 3/32 of one inch.
To measure fillet weld leg length, place one leg of the gauge on the plate and lower the other leg to the toe of the weld. Read the actual fillet weld leg length from this scale. This leg length reads 1/2 of one inch.
A similar procedure can be used to measure butt weld reinforcement. Place one leg of the gauge on the plate and lower the other leg to the top of the butt weld. Again, read the measurement from this scale. This measurement reads 1/8 of one inch.
