Gas welding is the process in which a gas flame is used to raise the temperature of the metal to be joined. The metals are heated up to melting. The metal flows and on cooling it solidifies. A filler metal may be added to the flowing molten metal to fill up cavity made during the end preparation. Many combination of gases are used in Gas welding. But most common of these in oxygen and acetylene.
