Welding inspections gauges are available for checking alignment, checking dimensions before welding, verifying weld dimensions, and checking porosity of welds. Some gauges are multipurpose or single purpose. The gauge measures internal mismatch of pipe wall, scribe lines, weld fillet and crown height.
What is the most commonly used gauge in welding?
A weld gage is a simple hand-held device that lets the welder or weld inspector, check the size of the fillet. While several different types have been developed over the years the two most common are the Standard Fillet Weld Gage and the AWS Gage.
What is throat thickness of weld?
The throat of the weld is the distance from the center of the face to the root of the weld. Typically the depth of the throat should be at least as thick as the thickness of metal you are welding.
What does a bridge cam gauge measure?
The Bridge Cam Gauge, commonly known as the Cambridge gauge, is an accurate, sturdy gauge for both shop and field applications. It can measure fillet weld leg length and throat thickness, height of weld reinforcement, depth of undercut, misalignment and the angle of preparation.
How can you tell how thick your throat is welding?
To calculate the throat size from a given leg size: Throat = Leg / √2. For approximate size use 1.41 for √2 .

| Base metal thickness (T)a | Minimum size of fillet weldb | |
|---|---|---|
| in | mm | in |
| 1/4 < T < 1/2 | 6 < T < 12 | 3/16 |
| 1/2 < T < 3/4 | 12 < T < 20 | 1/4 |
| ¾ < T | 20 < T | 5/16 |
What thickness is 11 gauge?
15 U.S. Code § 206. Standard gauge for sheet and plate iron and steel

What is checked with weld fillet gauge?
Fillet Weld Gauge, Stainless Steel Fillet Weld Set Welder Inspection Gauge for Checking Leg Length and Throat Thickness for Professional Welders.
Which welding is strongest?
Bottom Line. TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.
What can I measure with the Bridge Cam gauge?
You can use the Bridge Cam Gauge to measure the following: 1. The angle of preparation from 0 to 60 deg 2. Excess weld metal ( welding cap or capping size ) 3. The depth of welding undercut or pitting 4. Fillet weld throat size 5. Fillet leg length 6. Misalignment ( high-low )
What are the gauges used in welding?
After welding the welds are inspected for size and shape by means of welding gauges. These are metal plates or high gauge-sheets with cuts corresponding to the cross-section of a given size and type of weld.
What is WG3 welding gauge?
Welding gauge WG3 Designed to measure the convexity of the weld angle edge preparation connected parts corner and butt welds, bevel edges in the preparation of the welded joints of parts, measuring the height of fillet weld leg, measuring the height of the roller gain clearance measurement in conjunction with the preparation of parts for welding.
What is the thickness of a fillet weld?
At B, throat thickness of the fillet weld is 5-6 mm which is a point on the gauge touching the centre of the face of the weld. On each gauge numerals are punched indicating the thickness of the work in millimeters for butt welds, and the leg in millimeters for fillet welds.
