Welding Chapter 48 Flashcards

An imaginary line through the length of a weld, perpendicular to the cross section, at its centre of gravity.

The retreat of the flame into the torch tip, followed by its immediate reappearance accompanied by noise and possible flameout.

<p>Weld Bead = A weld deposit resulting from a pass with a welding rod. Underbead Crack = A crack in the heat affected zone, generally not extending to the surface of the weld. Welding Transformer = The electrical transformer used for supplying desired voltage for welding. Forge Welding = The joint surfaces are heated, and pressure is applied to create a joint.</p> Signup and view all the answers
