Deep Throat Thickness Gauge

Product Information

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. 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 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? 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. 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?

Before measuring the welds using the fillet gauge- perform the visual inspection and decide the type of fillet weld for: 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.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? Cahz ah dung ina yuh dung ina yuh dung ina yuh throat gyal stop di noise mek mi cum ina yuh throat gyal Starting from the corner of the fillet, it is the maximum spread of the weld along the base and perpendicular of the right angled triangle that we just talked about above. See the illustration in the figure above. 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.

Bridge Cam Gauge is a versatile gauge as with one single gauge you can perform many tasks, such as: 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: 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 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 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.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. Below are the main uses of Bridge Cam Gauge, How to Use it for different measurements are listed with reference to pictures.

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