Friction seam welding is often preferred for materials that are inherently difficult to weld using traditional arc welding methods. 1. 13. Title: A21-desk. Edge weld symbols are used to specify edge welds on edge joints, flanged butt joints, or flanged corner joints. 3-38). Friction seam welding: High rotational speeds and pressure are used to generate heat and weld the seam through friction. So, Weld Symbol supplements a Welding Symbol to provide full details about the welding requirements. The weld size is placed always on left side of the weld symbol (triangular shape). When seam welding extends for the full distance between abrupt changes in the direction of welding, a length dimension is not required on the welding symbol. Tee Joint: A joint which are two pieces of metal are perpendicular to each other. Termination of ntermittent "esistance 8eam +elding. Utilizing heat input, the weld melts into the other component by projecting through the top surface. The symbols for these grooves are nearly identical to the symbols that represent.
