A(n) ____ flame has an excess of fuel gas. This flame has the lowest temperature and may put extra carbon in the weld metal.

Question

Quizplus · Accepted Answer

A carburizing flame has an excess of fuel gas, which can lead to a lower temperature and can cause extra carbon to be added to the weld metal. This can result in a weaker weld with reduced corrosion resistance. The other options, oxidizing and neutral flames, have specific ratios of fuel to oxygen that are necessary for proper welding. The acetylene flame is a specific type of fuel used in welding, but it does not relate to the excess of fuel gas in a carburizing flame.
