Deep Throat Thickness Gauge

Product Information

Visual aids (magnifying glass, torch) and gauges are used to support the detection of welding discontinuities and to measure the size of welds in fabrication companies. 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. A mitre fillet weld is a weld with a triangular cross-section. It is strong but needs weld flushing to produce mitre weld. For special applications, it is used to join two pipes at an angle. 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. More precisely, this gage is used to ascertain whether the measurements of a fillet weld meet specified values or not (rather than making actual measurements of these values). How Do You Use A Fillet Weld Gauge?

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. As previously mentioned, caliper gauges are supplied with either dial or digital readouts. Digital caliper gauges will always be the most accurate type, given that the display can be up to 3 decimal places and eliminates human error when reading the scale. Dial caliper gauges are also supplied with different graduations depending on the level of accuracy required.For example, for the Bridge Cam gauge from Gal Gage, it’s good to use their calibration services. The calibration is carried out for: 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 Welders & Welding Inspectors use welding gauges to measure the weld size and to make sure that they are within the acceptance limit. Most specifications require convexity and concavity to be minimal, or to a specified minimum value. FAQs About Fillet Weld Gauges What Is A Fillet Weld Gauge?

Measuring the leg length of a Fillet weld with a bridge cam gauge is easy and fast. The gauge is placed on one member, allowing both resting areas of the gauge on the plate. Before measuring the welds using the fillet gauge- perform the visual inspection and decide the type of fillet weld for: 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. 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. 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.

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. 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. The leg length refers to the distance from the root to the toe and should be measured in both directions using fillet gauges. The fillet weld measurements are carried out using two approaches: One thing I can usually say about the .303 rifle is it will have been shot, usually shot a lot and accuracy does suffer after a while. Now accuracy is not always a good reason to buy a rifle and I have rifles here that will not shoot a hand span group at a 100 yet they are keepers, equally I have worked with rifles capable of shooting tiny groups at extremely long distances that have left me cold.

The most important fillet weld gauge to have in your arsenal is the common gauge. However, there are other gauges you might want to consider. Commonly, gages are used to declare a weld as ok/not ok, rather than making precise measurements. The AWS gage serves this purpose well. In dial models with smaller scales, the dial may rotate the full 360° multiple times if the measured depth is large. The user will need to account for this by counting the number of full rotations the dial completes during the operation and add these values onto the total depth value. The advantage to using dial models with smaller scales is that these will provide a more accurate measurement (for instance, a dial gauge with a 1mm scale has a 0.001mm graduation whereas a gauge with a 10mm scale has a 0.01mm graduation). Then study the article (especially the last paragraph of the "Gas erosion at throat" section) to understand that it's the relationship of the seated bullet to the leade that's critical for discouraging the projectile from yawing in the throat.Different models will also use different styles of scale. Some snap gauges will use an indicator-type dial with a linear scale, whereas others use a plus and minus format. In these models, the gauge is zeroed off with limits set at either side (left side is negative, meaning the measured object is smaller than the desired size, whereas the right side is positive, meaning the measured object is larger than the desired size). If the object falls outside either side’s tolerance, it will fail inspection. Similarly, for measuring the leg length on the vertical piece, position the gauge along the vertical part such that the gauge hugs the metal uniformly. Then move the slider such that it touches the horizontal metal. The extent of the movement of the slider can be seen on the gauge. This reading is the leg length of the fillet along the vertical base metal. 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. The main advantage of a concave fillet weld is that it is very strong and can support heavy loads. However, concave fillet welds are more difficult to create than other types of welds, so they are not always the best choice for every application. What is Convex fillet Weld? Similar to the measure of convexity, first find out the expected fillet size of the weld, by referring drawing or any other technical document.
