Exothermic cutting requires the base metal to be cleaned prior to cutting.

A. True
B. False


Sagot :

Final answer:

Exothermic cutting requires cleaning the base metal to facilitate the process by utilizing energy released in the exothermic reaction between oxygen and the metal.


Explanation:

Exothermic cutting requires the base metal to be cleaned to ensure a successful process. When oxygen reacts with the exposed metal during the cutting, it results in an exothermic reaction, releasing energy and increasing temperature. An example is the use of an oxyacetylene torch in exothermic cutting, where the combustion of acetylene in oxygen generates heat to melt the metal.
