Quizplus · Accepted Answer

Flux is a chemical substance that is used to prepare a metal surface for soldering or brazing by removing any oxides or impurities on the surface. This helps to ensure a strong, durable joint. Paste may contain flux, but not all pastes used in soldering and brazing contain flux. Sandcloth is used for cleaning and preparing the surface, but does not aid in making the joint. Lead is a metal that may be used in soldering, but is not always necessary and may not aid in making the joint.
