Deep Throat Thickness Gauge

Product Information

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. 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? 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. A concave fillet weld is a type of weld where the face profile dips inward and the throat size is smaller than leg length. This type of weld is good for cyclic loading, as it can withstand repeated stress without breaking.

Welders often strive to produce a convex fillet weld, as this type of weld face is typically seen as being more aesthetically pleasing than a concave weld face. How you use a fillet weld gauge largely depends on what you’re measuring. Above in the article, we saw how to use a fillet weld gauge for measuring leg length, throat, concavity, and convexity of a fillet weld. Often, rather than making accurate measurements of these dimensions, a gauge is only used to inspect whether weld meets the specified values or not. Like a go/no-go gauge. It can be difficult to answer this question. In general, most professionals select rugged leaf-type weld gauges, most often from stainless steel. These materials are highly durable, fast, and accurate. Some professionals prefer Bridge Cam or AWS gauges if they need a gagging fillet weld specifically. Final ThoughtsNext, you should select the standard fillet gauge side to be used for the fillet weld size measurements. If the weld is not within specification, it will not meet the strength requirements, which could lead to a failure in the weld. 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. 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.

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. 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. 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.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). Fillet welds and predominately used weld joint types in construction, structural and general fabrication although they are not used in critical weld joint locations. Get the best-discounted Fillet Gauges online 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. 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? 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

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. The DOVETAIL MEASURING GAUGE XS SIGHT SYSTEMS DOVETAIL MEASURING GAUGE is a must-have for professionals and DIY enthusiasts who want to achieve a precise and professional-looking dovetail sight installation. With its accuracy and ease of use, it saves time and reduces the chances of error, making it an excellent investment for those who frequently work with dovetail slots. 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.First find out the expected fillet size of the weld, by referring drawing or any other technical document. If you notice that the weld does not extend all the way to the Vertical Toe a.k.a “V. Toe” then your weld is undersized vertically and must be fixed.

And finally, to measure undercuts or pits, place the legs of the gauge squarely on the surface of the plate and lower the tip into the undercut or pit. The amount of undercut is read from this scale. This pit reads 1/16 of one inch or approx 1.6 mm. Watch this video of the Bridge Cam Gauge 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. Before measuring the welds using the fillet gauge- perform the visual inspection and decide the type of fillet weld for: SM134 Armourer's plug gauge .301" - Bore accept - Bore straightness - gauge must pass freely through entire barrel held vertically. 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.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
