Question

Quizplus · Accepted Answer

A neutral flame is the best choice for welding all metals, including cast iron, malleable iron, wrought iron, and high-strength rods. This flame has equal amounts of oxygen and acetylene, which ensures a balanced and consistent heat output for effective welding. Carburizing and oxidizing flames are not suitable for welding these types of metals as they can cause damage or produce inferior welds. Metal flames are not commonly used for welding and are instead used for cutting or heating metal.
