Deep Throat Thickness Gauge

Product Information

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). 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. 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. 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.

Single-purpose weld gauges are fantastic if you know exactly what purpose you need the device for. The gage can be used to make rapid measurements on a large number of welds one after another. 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?

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

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

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 This is a high quality product and performs as advertised, but not as easy to use or useful I first thought. It requires a lot of additional firearm knowledge to be a productive tool. A profitable service that every gunsmith should offer to shotgun shooters. Re-working an improper chamber with the Walker Gauges and proper chamber and Forcing Cone Reamers can reduce recoil, shot deformation, and improve patterns. The system was developed and proven by the late Ralph Walker, Selma, Alabama, gunsmith, writer and author, who had used it in his shop.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?

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. 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. 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. 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. In AWS-CWI certifications measurements of a fillet weld are taught using the Standard Fillet weld gauge set for the most commonly used weld sizes, say 1/8 inch to 1 inch as shown in the below picture.Then, place the gauge such that the beveled edges of the gauge rest squarely on the two adjoining surfaces of the fillet weld. The gap between the slider and the surface of the weld is a measure of the convexity. In this case, more gap means less convexity. Also it's an odd shape, I thought it would fold or disassemble to fit in a smaller slot in my tool box.
