Deep Throat Thickness Gauge

Product Information

Next, you should select the standard fillet gauge side to be used for the fillet weld size measurements. 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.

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. 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. The figure shown above is a theoretical concept of a filler weld– represented by an equilateral triangle. You will notice that an actual fillet weld is difficult to achieve with this profile unless external grinding or machining is applied on the fillet weld surface.Also it's an odd shape, I thought it would fold or disassemble to fit in a smaller slot in my tool box. 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. If the weld is not within specification, it will not meet the strength requirements, which could lead to a failure in the weld. 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? Throat size measurement is used in ISO & British inspection standards while leg length is used in AWS (Americans) & CSA (Canadian) welding inspection standards.

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. The AWS (Automatic Weld Size) gauge is considered a highly versatile tool. It is able to measure the size of your fillet weld, tolerance of convexity, tolerance of concavity, tolerance of underfill, and tolerance of reinforcement. If you want a great reliable gauge, the AWS is one of the best to get. 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. For example, for the Bridge Cam gauge from Gal Gage, it’s good to use their calibration services. The calibration is carried out for:Commonly, gages are used to declare a weld as ok/not ok, rather than making precise measurements. The AWS gage serves this purpose well. Similar to the measure of convexity, first find out the expected fillet size of the weld, by referring drawing or any other technical document. Like any tool, before you use your fillet weld gauge, you need to calibrate it first. All gauges used by professionals are often inspected and calibrated to ensure they meet the specified standards for effectiveness. 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. In fact I believe all new FAC holders should get out and shoot one at some point, just because. I have a modest collection of 303 Sporting and military rifles, including Lee Speed and postwar No1Mk3 commercial examples here in the armoury along with later ones such as the 1920 Lithgow below.

Before measuring the welds using the fillet gauge- perform the visual inspection and decide the type of fillet weld 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 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).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.
