Deep Throat Thickness Gauge

Product Information

Similar to the measure of convexity, first find out the expected fillet size of the weld, by referring drawing or any other technical document. Welders & Welding Inspectors use welding gauges to measure the weld size and to make sure that they are within the acceptance limit. 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. 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.

However, it is important to note that excessive convexity can actually have a negative impact on the overall strength of the weld, as it can create weld bumps that protrude outward from the surface. 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 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 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.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? 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.

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. 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.

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.

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. Bridge Cam Gauge is a versatile gauge as with one single gauge you can perform many tasks, such as: 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. 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.

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

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. 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. First find out the expected fillet size of the weld, by referring drawing or any other technical document. 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?
