These steps hold good for an AWS fillet gauge <\/a>(which finds extensive usage in US), although a variety of gauges of fascinatingly wide-ranging utility today inhabit the market.<\/p>\n\n\n\nA properly made fillet shows same leg length along the entire length of the weld.<\/p>\n\n\n\n
Checking Concavity Of The Fillet<\/h3>\n\n\n\n First find out the expected fillet size of the weld, by referring drawing or any other technical document. <\/p>\n\n\n\n
Then set the slider in the gauge to the required fillet size on the ‘concavity scale’.<\/p>\n\n\n\n
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 concavity. More gap means more concavity.<\/p>\n\n\n\n
Checking Convexity Of The Fillet<\/h3>\n\n\n\n Similar to the measure of convexity, first find out the expected fillet size of the weld, by referring drawing or any other technical document. <\/p>\n\n\n\n
Then set the slider in the gauge to the required fillet size on the ‘convexity scale’.<\/p>\n\n\n\n
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.<\/p>\n\n\n\n
Most specifications require convexity and concavity to be minimal, or to a specified minimum value.<\/p>\n\n\n\n
FAQs About Fillet Weld Gauges<\/h2>\n\n\n\nWhat Is A Fillet Weld Gauge?<\/h3>\n\n\n\n A fillet gauge is a measuring device that can gauge how convex or concave your welding surface is. It is primarily used by professional welders to ensure that the finished fillet weld is straight, accurate, and strong. It is most frequently used for measuring throat thickness and leg length.<\/p>\n\n\n\n
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).<\/p>\n\n\n\n
How Do You Use A Fillet Weld Gauge?<\/h3>\n\n\n\n How you use a fillet weld gauge largely depends on what you\u2019re 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.<\/p>\n\n\n\n
Either way, most fillet weld gauges require you to lay the gauge on your welding contraption. You will then look at how the weld lays across the gauge to determine the measurements.<\/p>\n\n\n\n
Do Weld Gauges Need To Be Calibrated?<\/h3>\n\n\n\n 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.<\/p>\n\n\n\n
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.<\/p>\n\n\n\n
What Fillet Weld Gauges Do Professionals Use?<\/h3>\n\n\n\n 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.<\/p>\n\n\n\n
Final Thoughts <\/h2>\n\n\n\n The fillet weld gauge is one of the most important tools for any welder to have, and equally important for a QC inspector. Although the device looks confusing, it is far from it. As long as you know what to look for, you will be able to measure both the throat thickness and leg length using this device with little trouble. It also gives a quick measure of concavity or convexity in a weld.<\/p>\n\n\n\n
Many gages in market can be used to measure weld reinforcement for butt welds too. Here are a few illustrations.<\/p>\n\n\n\n

Measuring reinforcement using a bridge cam gauge<\/figcaption><\/figure><\/div>\n\n\n\nYou will have to choose the most appropriate gauge for your use, depending on what you need to measure. Measuring the throat thickness is not the same as measuring the leg length. Still, you don\u2019t need a lot of expertise in order to do either.<\/p>\n\n\n\n
To ensure you get the right tool for your needs, carefully consider what kind of fillet weld gauge you need. The common, adjustable fillet weld gauge may be the most versatile, but an AWS or single-purpose weld gauge can be more specific and give you exact results based on your needs.<\/p>\n\n\n\n
