Did You Know?
1. Acetylene, often used for welding, was discovered in 1836 by a chemist named Edmund Davy.
2. While acetylene is commonly used for welding, it has another surprising application—it is also utilized as an anesthetic in dental surgeries.
3. Did you know that acetylene is the only fuel gas that can reach the necessary temperature to weld cast iron effectively?
4. Acetylene welding is known for producing a distinct and recognizable smell—similar to that of garlic or rotten eggs—due to impurities present in the gas.
5. Before acetylene became popular for welding, it was first used for lighting. The acetylene gas was burned in lamps, providing a bright and efficient alternative to the traditional oil or gas lamps of the time.
Acetylene’s High Heat And Safety For Welding
Acetylene is a widely used gas for welding due to its high heat output. When burned with oxygen, acetylene produces a flame temperature of approximately 3100 degrees Celsius. This intense heat is crucial for effectively gas welding steel, enabling the metal to reach the necessary temperature for proper fusion.
Another advantage of acetylene is its ability to create a reducing zone during the welding process. This reducing zone helps to clean the metal surface of impurities and oxides, ensuring better weld quality. A clean and properly prepared metal surface is essential for successful welding, and acetylene plays a vital role in achieving this.

- The high heat output of acetylene is crucial for effective gas welding of steel.
- Acetylene creates a reducing zone during the welding process, cleansing the metal surface and ensuring better weld quality.
The Efficiency And Effectiveness Of Acetylene For Welding
In addition to its high heat, acetylene is also known for its efficiency when used with oxygen. This gas mixture has a high combustion efficiency, meaning that it provides more heat per unit of gas consumed. As a result, welders can achieve their desired welding temperature with less cylinder handling, reducing the frequency of cylinder changes.
Compared to propane, acetylene has lower stoichiometric oxygen requirements. This means that it consumes less oxygen during the combustion process. By requiring less oxygen, acetylene allows for more efficient use of the oxygen supply. This can be particularly advantageous in cases where oxygen availability may be limited or when working in remote locations.
The Safe Handling And Transport Of Acetylene Cylinders
Safety is of utmost importance in any welding operation, and acetylene offers a high level of safety when handled and transported correctly. Acetylene cylinders are available in various sizes, providing flexibility for different welding needs. These cylinders are easy to source and transport, allowing welders to readily access the necessary equipment for their work.
Operational procedures related to acetylene cylinders have also been revised to enhance safety. In November 2012, the FRS (Fire and Rescue Service) changed its guidelines to allow for a specific cooling and monitoring protocol in the event of a fire involving acetylene cylinders. The updated procedure includes one-hour cooling of the cylinders followed by an additional hour of monitoring. These guidelines help to mitigate potential risks and ensure the safe handling of acetylene cylinders.

Frequently Asked Questions
Can you weld with acetylene?
Yes, acetylene can be used for welding. When combined with oxygen, acetylene produces a flame with an extremely high temperature, making it ideal for gas welding steel. This high flame temperature creates a reducing zone that efficiently cleans the metal surface during the welding process.
What type of welding uses acetylene?
Acetylene gas is primarily used in oxyacetylene welding. This type of welding relies on the combustion of acetylene and oxygen to create a high temperature flame that can melt and join metal pieces together. The acetylene gas provides the fuel for the combustion process, while the oxygen supports and intensifies the flame, resulting in a powerful welding technique often preferred for its versatility and portability.
Can you use acetylene for MIG welding?
Acetylene can indeed be used for MIG welding, but it is not a common choice due to its specialized nature. While gases like propane, butane, and natural gas are more commonly used in MIG welding guns, acetylene can be an option in certain specialized applications. However, its use in MIG welding is less common and reserved for specific needs where the unique properties of acetylene are required.
What gas is used in welding?
One commonly used gas in welding is argon gas. Argon is a shielding gas that helps to protect the weld from atmospheric contamination by providing a stable and inert environment. It allows for precise control of the welding process and produces high-quality welds. Another gas used in welding is acetylene, which is a fuel gas that provides a high heat source for welding and cutting applications. It is often combined with oxygen to create an oxyacetylene flame, which has a temperature that can exceed 6000 degrees Fahrenheit. This intense heat allows for effective and efficient welding and cutting processes.
