Oxy-acetylene welding

Advantage Fabricated Metals performs a number of welding processes. The two most common welding processes we use include TIG, an acronym for Tungsten Inert Gas welding and MIG, an acronym for Metal Inert Gas welding. TIG is also referred to as GTAW (Gas Tungsten Arc Welding) and Heliarc®. MIG also is referred to as GMAW (Gas Metal Arc Welding). We also provide oxy-acetylene welding.

Oxy-acetylene welding is a very common welding process. The use of oxygen and acetylene as welding gases dates back to the 1890’s. The combination of oxygen and acetylene produces a flame temperature over 6000 degrees Fahrenheit making it ideal for welding and cutting.

Characteristics of the oxy-acetylene welding process

Characteristics of the oxy-acetylene welding process include:

  • The use dual oxygen and acetylene gases stored under pressure in steel cylinders,
  • Its ability to switch quickly to a cutting process, by changing the welding tip to a cutting tip,
  • The high temperature the gas mixture attains,
  • The use of regulators to control gas flow and reduce pressure on both the oxygen and acetylene tanks,
  • The use of double line rubber hoses to conduct the gas from the tanks to the torch,
  • Melting the materials to be welded together,
  • The ability to regulate temperature by adjusting gas flow.

The illustration that follows provides a look at a typical oxy-acetylene welding process. The welding tip is mounted on the end of the torch handle and fuel and gas mixture pass through it to feed the flame. Welding tips have only one hole while cutting tips have a centrally located hole with a number of smaller holes located around it in a circular pattern. During cutting, the oxygen comes from the center hole and the preheat flames come from the holes around the center hole.

In oxy-acetylene welding, the flame produced by the combination of the gases melts the metal faces of the workpieces to be joined, causing them to flow together. A filler metal alloy is normally added and sometimes be used to prevent oxidation and to facilitate the metal union.

The molten metal has a tendency to pop and splatter as heat is applied and oxygen reacts with the superheated metal. It is critical that operators using the oxy-acetylene welding or cutting process wear proper gloves and use approved safety goggles or face shield. The goggles and/or face shield protect the eyes from sparks and flying hot metal particles. The goggles or face shield use special lenses to protect the eyes form light damage. A variety of lenses are used depending on the type of welding or cutting that needs to be done, the type of material, and the thickness of the material. If protective eye shielding is not used, painful burns can occur on the surface of the eye, and could result in permanent damage.
