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. Table 3 contains details of all supplementary symbols. 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. The arrow indicates the side of the joint where the weld is to be made. As used in the Australian steel fabrication industry. It usually involves preparing the. The four basic welding positions are: flat, horizontal, vertical, and overhead. 4. This type of weld is commonly used in applications where strength and aesthetics are important. There is a specific weld symbol for each of these weld types, which is just one small part of the entire welding symbol. Intermittent welds are to be doubled at the ends of all stiffening members andFillet Welds. Arrow. Design-related specifications, such as type, thickness, and length of weld, weld quality, surface treatment, filler material and testing specifications, can be indicated directly at the weld by means of the symbols given in this standard. The Weld Geometry allows two faces to be chosen so a weld bead can be laid between them. Each welding symbol has two segments: a horizontal reference segment and a leader. 3-27). A groove weld is made in a groove between workpieces or between workpiece edges. Weld symbols on the full reference line relates to welds on the arrow side of the plate being welded.
