Oxyacetylene is a high-temperature (up to 3,500°C) gas welding and cutting process using mixed oxygen and acetylene, ideal for welding, brazing, and cutting steel and other metals. It is versatile, portable, and allows precise heat control, but often causes material distortion and is slower than modern arc welding.
Process: Uses a torch to combine oxygen and fuel gas (usually acetylene) to produce a hot flame that melts metal edges and filler rods.
Flame Types: Operators adjust the gas mixture ratio to produce neutral (general welding), carburizing (hard surfacing), or oxidizing (brazing/cutting) flames.
Equipment: Includes oxygen/acetylene cylinders, regulators, hoses, and a blowpipe.
Applications: Widely used in engineering, maintenance, and fabrication for thin metal, welding repairs, and cutting steel.
Safety: Requires protective goggles, gloves, and clothing to guard against intense light, sparks, and molten slag
Welding: Joining thin metal sheets or pipes.
Cutting: Severing thick steel plates through oxidation.
Brazing & Soldering: Joining metals without melting the base material.
Heating: Bending, straightening, or loosening seized parts.
