What is gas welding?

Gas welding, also known as oxy-fuel welding, is a welding process that uses a fuel gas (typically acetylene) and oxygen to create a high-temperature flame to melt and join metals. It is commonly used for welding thin materials, repair work, and in situations where portability is required. The process involves directing the flame onto the joint between the metal pieces, melting them together, and sometimes adding a filler metal to create a strong weld.
