Final answer:
The statement is false. Oxyfuel welding is a versatile process used for various applications and can weld different types of metals.
Step-by-step explanation:
The statement 'Oxyfuel (OF) gas processes are the least versatile of the welding processes' is false. Oxyfuel welding uses a flame produced by the combustion of a fuel gas with oxygen to generate the heat required for welding. It is a versatile welding process that can be used for various applications, including cutting, brazing, soldering, and welding different types of metals.
For example, oxyfuel welding is commonly used in the automotive and construction industries. It can be used to weld materials like steel, cast iron, and copper. It is also used for repair work, such as fixing pipes or metal structures. Oxyfuel welding offers both precision and power, making it a valuable welding process.
