Why is brazing commonly used in welding processes?

It allows for stronger welds.
It requires less heat.
It generates less smoke.
It uses cheaper materials.

The correct answer is: It requires less heat.

Brazing is commonly used in welding processes because it requires less heat compared to other welding techniques. Brazing joins materials by melting a filler metal that is then drawn into the joint through capillary action. The lower heat requirement of brazing prevents the base metals from reaching their melting point, which can help to minimize distortion and warping of the materials being joined. Additionally, the lower heat input can reduce the likelihood of damaging the base metals or creating undesirable metallurgical changes.
