This article focusses on fillet welds: what is fillet weld, what electrode size should be used, how many passes should be used etc. Some of the terminology associated with fillet welds has been indicated in the above figure. Some information about fillet welds pertaining to ASME Section IX has been included at the latter stages of this article. <\/p>\n\n\n\n
The Section IX portion mainly addresses these questions: what does fillet size mean in Section IX? Does it indicate the fillet weld leg size? Or the throat size? How to qualify a welder for making fillet welds on coded jobs? How to qualify a WPS for making fillet welds in accordance with ASME Section IX?<\/p>\n\n\n\n
A fillet weld<\/strong><\/em> is a triangular weld used to join two surfaces that are at approximately right angles to each other. i.e., lap, tee, and corner joints are normally welded with fillet welds. A fillet weld can be made between two plates, resulting in tee joint<\/a>, corner joint<\/a> or lap joints; or it can be made between two pipes as well resulting in a circular weld.<\/p>\n\n\n\n The shape of the weld is generally triangular, and the surface may be of flat, convex or concave shape, depending upon the technique deployed by the welder. Fillet welds of flat shape are sometimes also termed as ‘mitre’ shape.<\/p>\n\n\n\n A fillet weld requires much less joint preparation than a groove weld, and is therefore a cost effective and faster option to join metals when strength of the joint isn’t a critical requirement.<\/p>\n\n\n\n A fillet weld should have a leg length equal to the plate thickness up to 3\/8-inch plate. For plate thicknesses 3\/8-inch and greater, a minimum of 3\/8-inch leg length is required on all welds. A fillet is also one of the types of welds<\/a> that is used to make socket welds.<\/p>\n\n\n\n
