Yet welding around the corners and across the toes of the flanges is difficult and may result in rapid melting at the corners and a resulting gouge during welding. Most, but not all fillet welds are of equal legs. Weld symbols on the dashed line relates to weld on the far side of the plate. 3. This symbol consists of a single line that connects two points on the weld joint. Flag symbol – Field weld/Made on site. Instead of using an arrow and saying ‘weld here’, a weld symbol carries more useful information that can be easily understood by the welder, engineer, foreman, supervisor and architect. They are explained, however, in AWS/ANSI A2. Examples are given to reinforce concepts related. These welds are commonly referred to as tee joints, which are two pieces of metal perpendicular to each other, or lap joints, which are two pieces of metal that overlap and are welded at the edges. Possible welds for lap joint: Fillet. exercise 2, vessel 24. Edge Weld Symbols.
