True or False: An oxidizing flame on an oxyacetylene torch is recommended for brazing.

An oxidizing flame on an oxyacetylene torch is not recommended for brazing primarily because this type of flame can introduce excess oxygen into the process, which can lead to oxidation of the base metal and the filler material. For brazing, a neutral flame is typically preferred, as it provides the right balance of oxygen and acetylene, preventing oxidation while still providing sufficient heat for effective melting and joining of the materials.

While there are certain applications or metals that might see different flame settings, in general, the oxidizing flame can damage delicate materials and compromise the integrity of the joint being created. This makes the statement false, as the proper flame condition for brazing should not be oxidizing.
