Oxy-Acetylene Welding Process

Flashcards covering key terms and concepts related to the Oxy-Acetylene welding process.

Oxy-Acetylene Process

A welding process where oxygen and acetylene gases are mixed and ignited to produce a very hot flame, used for fusion welding.

Fusion welding process

A type of welding where the materials are melted to join them together.

Flux coated filler rod

A rod used in welding that may provide additional material and causes a slag layer to form over the weld.

Oxidation prevention

An envelope made up of both oxygen and acetylene that prevents oxidation during the welding process.

Applications of Oxy-Acetylene welding

Suitable for light gauge metals, steel pipes, and vehicle repairs.

Pros of Oxy-Acetylene welding

Portable, requires no electrical power, cost-effective, versatile for various metals and functions.

Cons of Oxy-Acetylene welding

Potential for rough weld appearance, heat warping materials, not easily automatable, requires skilled operator.

Cylinders color coding

Oxygen cylinders are black, while acetylene cylinders are maroon to prevent mix-ups.

Hose color coding

Oxygen hoses are blue, while acetylene hoses are red.

Threading on connections

Acetylene connections have left-hand threads and oxygen connections have right-hand threads to prevent interchange.

Flashback arrestor

A safety device that prevents the feedback of gases and possible explosions during welding.

Dissolved Acetylene

Acetylene cylinders are filled with porous acetone to prevent explosions if the cylinder falls.
