Oxyacetylene welding

From GAWDAwiki

Oxyacetylene welding, also known as oxyfuel welding or simply gas welding, creates a flame through the combustion of oxygen and acetylene.

This operation for steel is performed without any flux while fluxes are required for welding particularly all other metals. Oxygen cutting is used for wrought iron, steel and cast iron.^[2]

Flame settings

Three flame settings are used in oxyacetylene welding.

1. Neutral flames contain equal levels of oxygen and acetylene.
2. Oxidizing flames contain more oxygen than acetylene.
3. Carburizing flames contain more acetylene than oxygen.

Equipment

Oxygen and acetylene gases are stored in steel cylinders, which deliver the gases to the blowpipe through attached regulators and hoses. Flashback is prevented through the use of flashback arrestors.^[1]
