Study Notes
Welding Processes
- Arc welding processes involve fusion obtained by heating with an electric arc or arcs, with or without the use of filler metal.
Welding Terminology
- Arc length: the distance between the tip of the electrode and the weld puddle.
- Electrode holder: a device used for mechanically holding the electrode.
Discontinuities
- Crack: a fracture type discontinuity characterized by a sharp tip and high ratio of length and width to opening displacement.
- Defect: a discontinuity or discontinuities which, by nature or accumulated effect, can affect the strength or functionality of a weld.
