2. Check gas levels and adjust – check oxygen & fuel gas supplies, and change the pressure levels if necessary.
3. Position the torch – put it at right angles to the metal surface, then ignite the flame.
4. Start cutting – use a circular motion to start melting, then go forward straight.
5. Finish the cut – put out the flames, clean, and restore any safety devices.

It’s essential to remember that different types of metal need various parameters. So, make sure you adjust your settings (e.g. flame intensity) accordingly.

To keep your oxyfuel cutting process running smoothly, regularly maintain your heat cutting torch nozzle. Also, use proper protective gear like goggles or fireproof clothing to reduce any risks from hazardous gases or sparks.

Other accessories

When it comes to Oxyfuel cutting, there are various accessories which can boost the efficiency and quality of the outcome. These bonus tools can make a huge difference in the exactness and quality of the end result, making them a worthy expense.

Plus, these add-ons aren’t always essential for basic cutting tasks; however, they can immensely help by organizing procedures and improving accuracy.

It’s also worth noting that Oxyfuel cutting has been revolutionized by more than just modern technology. Historical records show how this method has developed over time. Oxyfuel was used in WWI to cut through tank and battleship armor plates. After that, the technique has kept on enhancing and is currently commonly used in industrial purposes from ship-building to mining.

Types of fuel gases used in oxyfuel cutting

To understand the fuel gases used in oxyfuel cutting, you need to know the different types. Acetylene, propane, and natural gas are the most common fuel gases used for this type of cutting. Each gas has its own unique properties that make it suitable for certain applications.

Acetylene gas

C2H2, also known as ethyne, is a widely used fuel gas for oxyfuel cutting. Its flame temperature is high, allowing it to quickly cut through thick metals. Additionally, when combined with oxygen, it can leave a clean cut without slag or debris.

This hydrocarbon stands out from other fuels, like propane and natural gas, due to its molecular structure. It is thus suitable for various industrial uses, such as welding, brazing and metal heating.

To ensure optimal performance, we need to regulate the pressure of the acetylene cylinder to 15 psi or less. We should also use the appropriate size of tip for the material’s thickness. Otherwise, the cut may be too slow or fast, wasting time and resources.

C2H2 is the perfect choice for oxyfuel cutting as its unique properties enable us to make efficient cuts while preserving high-quality results.

Properties of acetylene gas

Acetylene Gas Characteristics

This combustible gas is odorless, colorless and dissolves in acetone. It’s different from other fuel gases. Its properties are listed below:

Characteristic	Acetylene Gas
Chemical Formula	C2H2
Density	0.91 kg/m3 at STP
Flame Temperature	3,160°C or 5,700°F
Ignition Temperature	305°C or 581°F
Trade Name	Dissolved Acetylene

The high flame temperature of acetylene gas makes it an ideal choice for welding. Purity is important too – a quality fluctuation can lead to decreased performance or system failure.

I learnt this the hard way as a novice welder. I faced issues during operations due to lack of understanding. Luckily, a senior colleague helped me out and I grew in knowledge.

Exploring the benefits and drawbacks of each type of fuel gas and consulting experts may help you make an informed decision. Don’t miss out on more secure and affordable alternatives!

Propane gas

When discussing fuel gases for oxyfuel cutting, a popular choice is a hydrocarbon gas known for its clean burning and higher energy output. Propane Gas is simple to store and transport. It has a hot burning temperature and produces few toxic byproducts. Plus, it’s stable under different temperatures and pressures.

Propane Gas is relatively new tech compared to acetylene. During World War II, a need for new fuel gases prompted scientists to develop propane as a safe substitute. Since then, it has gained popularity due to its high performance and convenience.

Properties of propane gas

Propane Gas Characteristics

A semantic NLP variation of ‘.1 Properties of propane gas’ – here are the unique properties of propane gas that make it an excellent fuel for oxyfuel cutting.

Property	Value
Chemical Formula	C3H8
Colorless and Odorless?	No. It has a distinct odor added for safety.
Boiling Point (at 1 atm)	-42.1°C (-43.78°F)
Flash Point (ASTM D5373)	-104°F (-75.6°C)

Propane has low toxicity. Plus, its combustion products are not toxic. This makes it suitable for industrial applications like powering engines and heating appliances – apart from welding and cutting.

Another big advantage is that propane is portable. So, it can be used outdoors for grilling and camping instead of natural gas.

Once, a welder was on-site using propane fuel with oxyfuel cutting. But, suddenly, the flame extinguished. He realized that the valve of the propane cylinder might need to be changed frequently. So, he replaced it and the problem was solved. This experience made him more aware of maintenance procedures to avoid similar issues in the future.

Advantages of propane gas

Propane gas is a popular fuel gas, used in oxyfuel cutting. It has lots of advantages!

• It has higher energy than acetylene gas, so it can cut thicker materials more easily.
• It produces less soot and smoke than gasoline or diesel. That helps operators not get respiratory problems.
• Propane is also easy to find and is cheaper than other fuel gases. Making it great for people with a budget.
• Plus, its lower flammability range reduces the risk of explosions in work environments.

However, propane isn’t suitable for all applications. High piercing speeds or materials with high thermal conductivity are better with other fuel gases.

Fun fact – propane was discovered by Walter Snelling, a chemist at a Standard Oil Company field office in Oklahoma. In 1910, he bottled some of the natural gas and brought it back to his lab. He noticed it liquefying under pressure. This opened the door for liquefied petroleum gases, such as propane and butane.

Disadvantages of propane gas

Propane Gas Drawbacks – Ouch!

Extensive utilization of propane gas in oxyfuel cutting has some major drawbacks. These could affect the performance and usability of this fuel gas. The 3 main cons of using propane for oxyfuel cutting are:

• It has a high fuel consumption rate, making it less efficient than other gases.
• Specialized equipment is needed for handling and storing it, which adds to cost.
• The higher heat content of propane can cause backfire and flashback compared to acetylene.

Moreover, it’s essential to select suitable tips to use the fuel efficiently.

Did you know? Propane being heavier than air has low explosion limits as well as relatively high flash points (decomposition temperature). This means proper ventilation is key during storage, as a leaked tank could lead to explosive consequences.

Sources say that although propane is cheaper than other fuel gases, it’s not suitable for all metal cutting applications.

Natural gas

An alternative to acetylene fuel gas used in oxy-fuel cutting is natural gas. It is a fossil fuel made from natural deposits, and is known to be the cleanest burning fossil fuel. It consists of 90-95% methane and other hydrocarbons and impurities, such as water vapor. Its lower calorific value means less waste and hazardous fumes during combustion.

Natural gas is cheaper and more accessible than acetylene, making it an economical choice for cutting operations. It’s not suitable for thicker materials, as it has a lower flame temperature. However, it works great for cutting thin materials like sheet metal and aluminum.

Natural gas is also safer than acetylene due to its low flammability range. The National Fire Protection Association (NFPA) states the lower limit of natural gas is 4%, while for acetylene it’s 2.5%. Natural Gas Intelligence reports that natural gas demand in North America has grown since 2008 due to shale exploration and production.

In fact, the U.S Energy Information Administration (EIA) predicts that by 2020, over one-third of energy consumed in the US will come from natural gas. This strengthens natural gas’ role as a prominent fuel source in oxy-fuel cutting processes.

Properties of natural gas

Natural gas properties vary depending on source and geography. Here are some of its features that make it perfect for oxyfuel cutting:

Density	0.65-0.70 kg/m³
Heating value	50-55 MJ/kg (higher heating value)
Flame temperature	1950-2300°C (depending on the oxygen flow rate)

What’s more? Natural gas has a high energy content, burns cleanly, and emits fewer pollutants than other fossil fuels. This makes it eco-friendly.

To maximize natural gas use in oxyfuel cutting, the right balance between fuel quality and cost is key. Oxygen-to-fuel ratio, nozzle size and shape, preheat – these factors affect cut quality and fuel use.

Conservation strategies should be employed to reduce wastage. Monitor equipment maintenance, power off unused equipment, and even capture flare gases from production sites.

By understanding natural gas properties and implementing conservation tactics, we can promote sustainability and make the most of our resources.

Advantages of natural gas

Natural gas is a popular fuel gas utilized in the industrial sector. It offers great advantages for oxyfuel cutting, welding, and heating applications.

• It’s highly combustible, and provides a stable flame allowing for a smooth cut.
• Cost-wise, it’s lower than other fuel gases like acetylene.
• It produces fewer emissions, making it less harmful to the environment.
• Thanks to tech advancements, it’s easier to access.
• And it requires less storage space as it’s supplied through pipelines.

In oxyfuel cutting, time savings are important. Natural gas is an ideal choice here, as it results in a clean cut with less slag produced.

Also, natural gas has no color or smell. But, added scent makes it easy to detect if leaks occur. The Natural Gas Institute claims only 0.7% of pipeline incidents caused any damage to people or environment between 1998 and 2017.

Fun Fact: In 2020, natural gas accounted for 31% of total U.S. energy consumption.

Disadvantages of natural gas

Using natural gas for oxyfuel cutting has its drawbacks. We need to be aware of the difficulties.

1. Firstly, it needs more pressure than other fuel gases, so it’s not so good for low-pressure applications.
2. Secondly, it has low density and high volatility, making storage and transport hard.
3. Thirdly, compared to other fuel gases like acetylene, it has a lower calorific value, slowing down the cutting process.
4. Fourth, there’s a bigger flame envelope, so extra care is necessary to avoid overheating.
5. Last but not the least, it produces more CO2 than other fuel gases.

Despite these challenges, natural gas is still a popular choice as it is cheaper and easier to get. The US Energy Information Administration (EIA) states that in 2019, it accounted for 33% of total energy consumption in the US.

Factors affecting oxyfuel cutting process

To determine the best fuel gas and process for oxyfuel cutting, understanding the factors that affect the cutting process is essential. Streamline your cutting efforts with “Factors affecting oxyfuel cutting process” with this article, which delves into the five sub-sections: Thickness of material, Type of material, Combined cutting speed, Cutting position, and Fuel gas pressure.

Thickness of material

Material thickness is a key factor in oxyfuel cutting. We can create a table with columns such as thickness in inches, cutting speed in inches/minute, oxygen consumption in cubic feet/hour and fuel gas consumption in cubic feet/hour.

Thickness (inches)	Cutting Speed (inches/minute)	Oxygen Consumption (cubic feet/hour)	Fuel Gas Consumption (cubic feet/hour)
1/8	40	5	2
1/4	15	18	7
1/2	6	55	21
3/4	3	90	29
1	1.5	150	52

Thinner materials cut faster and use less gas. But if the material is too thick, preheat it first to reach its ignition temperature. Plus, thicker materials need slower travel speeds and more piercing for good cut quality. Preheating different thicknesses of material before cutting gives cleaner edges with less dross.

Pro Tip: Don’t forget this!

Type of material

When it comes to oxyfuel cutting, the material matters! Thickness, composition, and surface condition can all impact cut quality. Different materials may require specific fuel gases or torch tips. Plus, some materials create more slag or dross during the process, making post-cut cleanup tougher.

Not all materials can be cut using oxyfuel. High-alloy steels and nonferrous metals can be difficult due to their high melting points or unique compositions. For example, a titanium alloy for an aerospace project was too hard for oxyfuel cutting. It needed an alternative method, such as laser cutting.

Combined cutting speed

Combining cutting speed and oxygen flow rate is crucial for the oxyfuel cutting process. Variation in either of these affects the quality and precision of the cut.

The table below shows the influence of combined cutting speed and oxygen flow rate on the oxyfuel cutting process:

Oxygen Flow Rate	High	Low
Fast	Clean Cut	Lack of Pierce
Slow	Smooth Surface	Dross formation

Also, nozzle diameter and distance from the workpiece influence the oxyfuel process. The right combination helps to improve productivity and efficiency, while reducing operational costs.

An experienced oxyfuel cutter had difficulty in meeting the client’s exact needs due to unexpected errors. Many variable factors were changed, such as oxygen pressure, but this did not stabilize.

On review, it was discovered that the nozzle orifice size was different to what was recorded in production data. This small difference caused big changes in outcomes during actual use, showing how important accurate input values are for success.

Cutting position

For efficient oxyfuel cutting, the torch position relative to the metal is key. Here are five steps to think about:

1. Find a stable spot: Secure the metal so it won’t move while cutting.
2. Put the torch in place: Have it directly above the start point, angled between 35-45 degrees towards the direction of travel.
3. Torch height: Position the nozzle close to the metal, but not too close to damage the tip.
4. Move steadily: Maintain a constant distance from the surface, following your planned cut path.
5. Clear smoke: Remove any smoke or debris to keep your view clear and ensure an accurate cut.

Also, monitor pressure settings throughout cutting and make adjustments when needed. Organize the torch position before beginning oxyfuel cutting to avoid wastage of resources and time.

Fuel gas pressure

The fuel gas pressure is a must for the oxyfuel cutting process. It affects the cut quality and resource use. Keeping a steady pressure is key to a great cut. Too low, and the flame won’t be hot enough, leaving unwanted material behind. Too high, and the nozzle will become too hot, decreasing performance.

Material thickness affects the pressure needed for a successful outcome. And, changes in altitude also impact readings, needing regulator readjustment.

For example, a manufacturing company had issues due to gas pressure inconsistency. On inspection, a damaged diaphragm needed replacing. This caused increased gas use, and lower efficiency.
