Deep Throat Thickness Gauge

Product Information

There are many different types of welding gauges used for inspection although Bridge Cam Gauge or also called Cambridge Gauge is a simple, versatile, accurate, easy to use, and handy welding gauge.

First find out the expected fillet size of the weld, by referring drawing or any other technical document. Commonly, gages are used to declare a weld as ok/not ok, rather than making precise measurements. The AWS gage serves this purpose well. Additionally, it should be noted that there is no added benefit to having an excessively convex weld; thus, welders should focus on creating a balance between aesthetics and functionality. What is Mitre fillet Weld? The following steps hold good for the gauges shown in the pictures. There are of course other kinds of gauges available as well in the market.

Once the gauge is positioned thus, move the slider in the gauge such that it touches the vertical base metal. The extent of the movement can be seen on the scale that is imprinted on the gauge. This reading is the leg length on the horizontal part. Other features which can be found in certain snap gauge series is IP54 protection (prevents ingress of dust which causes harm and protects against liquids splashing from any angle), data output capability and manufacturer’s inspection certificates traceable to DKD. Adjustable fillet weld gauges are great because they are convenient and do not require you to carry around as many tools. How to Use a Fillet Weld Gauge SKU: F30.0100 Category: Welding Inspection Description Product Information 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 millimetres.

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. Fillet weld is specified by a size known as either Throat size (given as a) or leg length (given as z). You can use fillet weld size formula to calculate the Fillet Weld size.

The fillet weld measurements are carried out using two approaches: 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.Next, you should select the standard fillet gauge side to be used for the fillet weld size measurements. Measurement of the Leg Length: Where leg length (z) means the dimension from the root point to the weld toe. So, two leg lengths are there for fillet weld shown in the below figure as L1 & L2. These leg lengths are shown as usually as Z1 & Z2 in the code or standards. There are other kind of gages available in the market too, that do not involve any slider in the instrument, and only involve putting the instrument on the fillet, and looking up a direct reading for measuring the throat size of the fillet weld. SM134 Armourer's plug gauge .301" - Bore accept - Bore straightness - gauge must pass freely through entire barrel held vertically.

In a similar fashion, the gauge can be used for measuring leg length of a fillet in any position. Only one thing needs to be remembered, the gauge must be suitable for the fillet size that needs to be inspected. If the weld is not within specification, it will not meet the strength requirements, which could lead to a failure in the weld. These steps hold good for an AWS fillet gauge (which finds extensive usage in US), although a variety of gauges of fascinatingly wide-ranging utility today inhabit the market.SM74 Armourer's plug gauge .306" - Barrel wear, - remainder of barrel life. No 1 Mk 1. Note: SM74 is for use in rifles and Bren machinegun. Bridge Cam Gauge is a versatile gauge as with one single gauge you can perform many tasks, such as: Generally, the gauges in today’s market come imprinted with values on the surface of the gauge. The gauges are single piece items, made up of stainless steels, and can be put to rugged use to make a large number of inspections before the gauge becomes worn out and not accurate enough. The gage is then simply replaced with a new one, as these gauges come at affordable prices. What Fillet Weld Gauges Do Professionals Use? Primarily these comments are on erosion gauges in general, not this individual product. First you have to keep detailed records for a long time and you have to be firing a lot of rounds. You have to develop a technique of reading the gauge that is exactly the same each time. The depth reading you record can vary with the position of your head. Additionally the gauge doesn't really give you a failure point but rather a relative change over time. So you have to record your first reading then compare subsequent readings to get the relative change in wear. Since there really isn't any "failure" point, you just see slowly deteriorating accuracy. So unless you compare accuracy against throat erosion, then you don't really know what an individual reading means.

Welders & Welding Inspectors use welding gauges to measure the weld size and to make sure that they are within the acceptance limit. If there is a space between this protrusion and the weld, the weld is concave, which it should not be. You will need to adjust your welding so that it fits appropriately. For example, for the Bridge Cam gauge from Gal Gage, it’s good to use their calibration services. The calibration is carried out for:When we design fillet welds, the shear stress calculation is based on the throat size (a) of the fillet weld. we can convert leg size (z) to throat size (a) using the below simple equation:
