A(n) ____ flame has an excess of oxygen. This flame has the highest temperature and may put oxides in the weld metal.

Question

Quizplus · Accepted Answer

An oxidizing flame contains excess oxygen and produces the highest flame temperature. However, this flame can put oxides in the weld metal, which can lead to defects in the weld. Acetylene produces a carburizing flame, which contains excess fuel gas and can cause carbon buildup in the weld. A neutral flame has equal amounts of fuel gas and oxygen and is typically used for general welding applications.
