Interpreting metal fab drawings A longitudinal weld is a type of welding joint in which two edges of a rolled material are welded along the lengthwise direction of the part. Friction seam welding: High rotational speeds and pressure are used to generate heat and weld the seam through friction. The symbols in this book are a representation of what weld and welding symbols look like. There are, therefore, often several ways to specify a given weld. indd 166 26/09/15 4:49 pm Seam Welds The seam-welding symbol indicates a weld that takes place between the faying surfaces of a lap joint that may be composed of two or more lapped pieces. 1.

Which type of weld joint can be fitted together so that the joint forms a V-groove or square butt joint? outside corner. 3. Most seam welding processes produce a continuous or intermittent seam weld near the edge of two overlapped metals by using two machine driven roller electrodes. The weld symbols inside the weld marks indicate the weld properties defined for the model weld in the model or for the drawing weld mark in the drawing. In a HV seam, only one workpiece is bevelled and the other is straight, so that the root is even more pointed than in a V seam (halved). This is a manufacturing drawing. 2.
