Positions — Pipe Weld
In the world of structural and piping welding, the position of the weld is not a mere logistical detail; it is the primary determinant of technique, filler metal selection, procedural qualification, and welder skill. Unlike flat plate welding, where the workpiece can often be manipulated to a favorable position, pipe welding demands that the welder adapt to a fixed, often unforgiving, geometry. The classification of pipe weld positions, standardized by the American Welding Society (AWS) and the American Society of Mechanical Engineers (ASME), provides a universal language for this challenge.
