AG Mechanics CDE Practice Exam

Which process uses both oxygen and acetylene for cutting or welding?

1. Brazing

2. Carbon Arc Welding

3. Oxyacetylene

4. Plasma Cutting

The correct answer is: Oxyacetylene

Oxyacetylene uses both oxygen and acetylene for cutting and welding processes. Brazing, on the other hand, uses a lower temperature and a brass or bronze filler metal to join two pieces of metal together. Carbon Arc Welding is a type of welding that uses a carbon electrode to create an arc and join two pieces of metal together. Plasma Cutting uses a plasma torch to melt and cut through metal, but it does not utilize both oxygen and acetylene like oxyacetylene does. Therefore, the best answer for this question is C Oxyacetylene.
