Acetylene

Acetylene is the most commonly used fuel gas in gas welding. It burns with oxygen at high temperatures to produce a high-temperature, high-energy flame. The flame can melt the metal and quickly reduce the oxides in the molten pool while melting. Acetylene can also be used for cutting and brazing, etc. The following matters need to be noted when using it:
 

1. When using acetylene gas cylinders, be sure to check whether the bottle body is damaged, whether the bottle valve and bottle mouth are leaking, etc. to ensure its safety.

2. To prevent gas leakage and pipeline damage, be sure to use professional equipment and follow the correct operating procedures to avoid hurting yourself and others during operation.

3. Avoid using acetylene flames for a long time to avoid explosions and other dangers. At the same time, avoid the flying of calcium oxide dust in large quantities and avoid inhalation.

Oxygen

Oxygen is an oxidant in gas welding. The mixed gas with acetylene will continuously supply oxygen during combustion, thereby making the flame temperature higher. When using oxygen, the following matters need to be noted:
 

1. Oxygen must be dried to prevent impurities such as moisture and grease from affecting the welding quality.

2. Avoid excessive oxygen supply during use to avoid explosion or unstable combustion.

3. For oxygen in the air, keep it away from flammable and explosive dangerous substances to avoid fire and explosion.
 

In short, gas welding is a common welding method, and the two commonly used gases are acetylene and oxygen. When using gas welding, you need to pay attention to the safety of equipment such as gas cylinders and pipelines, as well as the amount of gas used, temperature and other details, so as to ensure the quality of the substrate and the safety of the operator.
