What is the procedure in operating oxy-acetylene welding?
Open the acetylene blowpipe valve slightly and light the blowpipe with a flint lighter. Continue to slowly open the acetylene valve until the flame no longer produces soot. Slowly open the oxygen blowpipe valve until a neutral flame is produced.
What are the safety procedures for gas welding?
General Gas Welding Safety Tips
- Inspect equipment for leaks at all connections using approved leak-test solution.
- Inspect hoses for leaks and worn places.
- Replace bad hoses.
- Protect hoses and cylinders from sparks, flames, and hot metal.
- Use a flint lighter to ignite the flame.
What are the safety procedure in opening the acetylene?
Open the valve on the acetylene cylinder no more than three-fourths of a turn so it can be closed quickly in case of emergency. Open the valve on the oxygen tank fully. While welding or cutting, leave the valve wrench in position. Keep the tip pointed away from your body.
What are the three types of flame in oxy acetylene welding?
There are three types of flames natural flame, carburizing flame and oxidizing flame. Natural flame has synchronized mixture of fuel and oxygen, carburizing flame has more fuel and oxidizing flame has more oxygen. Different material used different flames according to weld condition.
What are the 4 types of welding process?
There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW).
What PPE is required for oxy acetylene?
5.1 Safety procedures when working with oxyacetylene welding equipment. Wear personal protective equipment. Wear welding gloves, helmet, leather apron, welding chaps, leather boots, welding goggles, and other personal protective equipment to help prevent weld burns and injury.
How do you test acetylene?
Test for acetylene leaks first.
- Use the Safetest Leak Detection Spray.
- Spray directly onto the joints and connections.
- Check that torch valves are closed and that regulators are set to zero outlet pressure.
- Open acetylene cylinder valve very slowly (sudden opening may cause damage to the regulator)
What are the 4 types of welding PDF?

What is the temperature of neutral flame?
In the neutral flame, the temperature at the inner cone tip is approximately 5850ºF (3232ºC), while at the end of the outer sheath or envelope the temperature drops to approximately 2300ºF (1260ºC). This variation within the flame permits some temperature control when making a weld.
