Principles of GMAW Exam Questions And
Answers
amperage - - -
correct answer ✅A measurement that indicates the amount of
current flowing in a circuit, which is measured in amperes
constant current - - -
correct answer ✅Welding using a current that varies slightly with
changes in voltage. Constant current, or CC, is often used in
shielded metal arc welding (SMAW) and gas tungsten arc welding
(GTAW)
constant voltage - - -
correct answer ✅Welding using a voltage that varies slightly with
changes in current. Constant voltage, or CV, is often used for gas
metal arc welding (GMAW) and flux-cored arc welding (FCAW)
contact tip to work distance - - -
correct answer ✅The distance from the end of the contact tip to
the surface of a workpiece. As contact tip to work distance
increases, the welding current decreases
electrode extension - - -
correct answer ✅For gas metal arc welding, flux cored arc welding,
and submerged arc welding, the length of unmelted electrode
