- The Bridge Cam Gauge by GAL GAGE Company is one of our most versatile gauges available. With it, you can perform several different types of measurements of welds in both inches or millimeters.
With this one, versatile tool, you can measure:
* Angle of preparation
* Outside misalignment
* Weld reinforcement
* Fillet Weld throat dimension
* Fillet Weld leg length and undercuts and pits
To measure the angle of preparation of this pipe, place the legs of the gauge squarely on the surface of the pipe and lower the rotating segment until it rests squarely on the bevel. This bevel angle measures approximately 42 degrees.
To easily measure outside misalignment, rest the legs of the gauge squarely on one surface of the pipe and lower the tip until it comes in contact the other pipe. The amount of misalignment is then read from this scale. This misalignment measures 3/32 of one inch or 2.3 mm
To measure weld reinforcement, lower the legs of the gauge to the surface of the plate. Then, using the tip, place it at the highest point on the weld. The Weld reinforcement dimension is again read from this scale. This weld reinforcement measures 1/8 of one inch or approx 3.1 mm
Now lets measure the actual fillet weld throat dimension using the miter slide on the Bridge Cam gauge. First, extend the slide as far as it will go, place the tip of the slide on the face of the weld and lower the gauge until it squarely contacts the surface of both plates. The actual throat dimension is then read from this scale. It reads just under 3/8 of one inch, or approximately 9 millimeters. Turn the gauge over and the scale on the back will also give you the theoretical weld size. In this case, 1/2 of one inch.
You can also use the slide as a go-nogo gauge. Simply remove the locking screw, flip the slide over to the theoretical side and reassemble the gauge. Use the increments to set the slide to match the leg length. In this case a 1/2 inch weld is specified. Set the slide to 1/2 inch and lock the screw. The gauge indicates this is an acceptable amount of weld.
To measure fillet weld leg length, rest the legs of the gauge on the surface of the plate, then rotate the tip, to the toe of the weld. The actual leg length is read from this scale. This measurement should read one half of one inch or approx 12.7 mm.
And finally, to measure undercuts or pits, place the legs of the gauge squarely on the surface of the plate and lower the tip into the undercut or pit. The amount of undercut is read from this scale. This pit reads 1/16 of one inch or approx 1.6 mm.
This Bridge Cam gauge is available individually from GAL GAGE COMPANY or it is included in our complete set of gauges available in our Briefcase Large Tool Kit.

The radius gauge does have a manufactures tolerance, and sometimes they are out of that tolerance regardless of how good your eyeballs are. Kudos to you convincing your auditor that you don’t need of them calibrated.
To ensure that your measurements are correct, your gauges will need to be checked occasionally for wear and that the gauges have not been damaged.
Also, the markings on any gauge, from any source are for reference purposes only and must regularly be reconfirmed / recertified.
Final note, if your systems / auditors call for a periodic recalibration, it must be done for compliance purposes.
Excellent video thank you!
Very nice video...got good measuring tips
Thank you Sir,,,,,,,,,,,Very Good Video!
Hi good measuring instrument. Can we use this instrument for measuring misalignment of 0.5 mm and less..???
The Bridge Cam can go to .5mm, no smaller.
How we can check the weld size 3x45 , whereas 3 in mm and 45 in degree .kindly reply
I did not hear about and no information available on google , how to and where to avail it . you have it kindly upload video .
For best results, you'll want to try our Skew-T Gauge, Cat # 9c:

When conducting a Pit read, what measurement is each line?
Great question! Each line is 1/32"
And for Metric, each line is 1 millimeter.
Are those sample got rejected?
The Bridge Cam Gauge by GAL GAGE Company is a very useful tool to accurately measure welds to assist in complying with the needed requirements to pass inspections.

What is the reference standard for all welding gauges ?
Terrific question! The reference standard for all welding gauges is N.I.S.T. (National Institute of Standards and Technology).
@@galgage could u share it's Link
@@galgage because I search at many times I can't get it. Please help me to purchase it.

@galgage thanks for your help. This is a catalog. I need the N.I.S.T. reference standard for calibration purpose.
