Quizplus · Accepted Answer

Fluxing materials are used for welding because some metals are reactive to the atmosphere when heated. The flux helps to protect the metal from oxidation and other atmospheric reactions, ensuring a clean and strong weld. Choices A, C, and D are incorrect because fluxing materials are not primarily used for these purposes.
