Final answer:
Air Carbon Arc Cutting (CAC-A) is a process used in engineering for cutting and welding metals using an electric arc and compressed air to remove molten metal.
Step-by-step explanation:
The correct answer is option Engineering.
Air Carbon Arc Cutting (CAC-A) is a process used in engineering for cutting and welding metals. It involves using an electric arc and a stream of compressed air to remove the molten metal. This method is commonly used in industries like construction and fabrication.
During the process, the high temperature of the arc melts the metal, and the compressed air blows away the molten metal, creating a clean cut. It is an effective method for cutting thick metal plates and removing defective welds.
The correct answer is option Engineering. Air Carbon Arc Cutting (CAC-A) is an arc cutting process where an electric arc is generated between the tip of a carbon electrode and the metal that is being cut.
This high-temperature arc melts the metal, while a continuous blast of air swiftly removes the molten metal from the cut area.
It's a process distinct from oxyacetylene cutting, which uses a combination of oxygen and acetylene to create a flame that can cut through metals.
Notably, most acetylene is not used for cutting or welding but is instead converted into chemical intermediates for the production of vinyl and acrylic plastics, as well as fibers, resins, and various other products.
