Question: 1 / 400

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

Brazing

Carbon Arc Welding

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.
