Among Welding Gases, Acetylene Takes Top Honors For Versatility

Acetylene is like the Swiss Army knife of welding gases. Acetylene is like the Swiss Army knife of welding gases.It’s extremely versatile and able to fulfill several different functions in the workshop. This versatility makes it a great choice for welders who work with a variety of different materials and don’t want to break their budgets.

What Is Acetylene?

Acetylene is a colorless and odorless gas with an extremely high flame temperature of more than 3,600 K. It is the hottest burning commonly available fuel gas. This hot flame temperature gives it an advantage over other types welding gases, whose lower flame temperatures limit the types of materials that can be welded. Acetylene can be used on the following materials:

  • carbon steels
  • low-alloy steels
  • stainless steel
  • aluminum alloys
  • copper alloys
  • nickel alloys
  • cast iron

Since it runs hotter than other welding gases, it can cut and heat materials; other gases can’t do this.

Acetylene and Welding

Although welding with acetylene is less popular these days now that arc-welding has advanced, it is still a worthwhile technique if only because of its’ versatility. When paired with oxygen, the gas is capable of welding a wide variety of materials. Welders can even use the same welding equipment for many different jobs. Just by changing attachments on the torch, the process can be changed from heating to cutting to welding. Without oxy-acetylene, you’d likely have to change welding gases and equipment for each job, adding to expenses and increasing downtime. There are also the storage implications to consider. Using different gases for different materials means you need different equipment and will have more cylinders on hand to store in the work area.

Liquid Oxygen: Creating A Liquid From A Gas

If you have ever wondered about the differences between liquid oxygen and gaseous oxygen, we’re here to help! The fact that a gas can also be aHospital operating room using liquid oxygen. liquid can be confusing but it all comes down to simple science.

First things first: there is no fundamental difference between liquid oxygen and gaseous oxygen. Oxygen is a gas in its’ natural form here on Earth, but by cooling it, we are able to condense the gas to the point that it becomes liquid. How cold does it have to be to condense? Well, the boiling point of liquid oxygen is –183°C (–297°F). That means liquid oxygen converts back to a gas at that temperature. Because of this extremely cold liquid state, liquid oxygen is a cryogenic material similar to liquid nitrogen and liquid helium. Those extremely cold temperatures are one reason why there are such strong warnings about how to properly handle liquid oxygen. Even our coldest Canadian winter air is warmer than the boiling point of liquid oxygen! Protecting liquid oxygen from ambient temperatures is vital to safe handling.

Differences Between Liquid Oxygen And Gaseous Oxygen

Liquid and gaseous oxygen aren’t that different. Neither is flammable by itself but both are strong oxidizers and can cause materials that burn in air to react more vigorously. Their differences mainly come down to storage. By cooling gaseous oxygen, it can be converted to a liquid. This condenses the oxygen and allows a larger amount of the element to be stored in a small space. When the liquid is warmed back up, it expands 860 times to become a gas again.

The advantages of this type of condensation and expansion are enormous. Liquid oxygen storage is less bulky, less expensive, and more easily handled/transported than gaseous oxygen storage. Containers must meet strict requirements to protect people from the cold temperature and to prevent the oxygen from expanding.

Since so many other gases react in the presence of oxygen, it’s very widely used in the metalworking and welding industries to melt, cut, weld, harden, and clean various materials.

Arrange Liquid Oxygen Delivery From Josef Gas

Josef Gas carries pure oxygen and oxygen blends in cylinders and tanks of various sizes to meet many different needs. We supply small, portable cylinders for the home hobbyist or small job specialist as well as larger tanks and liquid cylinders for bigger jobs. Cylinders are filled on-site using high-capacity computer-controlled weigh scales to ensure consistent and accurate filling.

Surprising Places You’ll Find Industrial Gases In Brampton This Holiday Season

The holiday season is here! Party balloons tied in bunches, floating filled with industrial gas. We thought this would be the perfect time to create a fun post about where you can find industrial gases in Brampton this time of year. While not typically associated with holidays, industrial gases actually play a very important part in the festivities. Here’s a look at several ways that industrial gases support holiday fun.

Holiday Uses For Industrial Gases

  • Party decorations. From schools to office parties to family gatherings, you’ll find parties outfitted with balloons – and helium is to thank for keeping those balloons afloat! Even the balloons that don’t float were probably filled with an industrial gas – unless you had a lot of helpers on hand to share their lung power!
  • Holiday drinks. What are the holidays without a few special beverages? Industrial gases like carbon dioxide and nitrogen play an important role in beverage manufacturing, preservation, and dispensing from beers and lagers to wines, sodas, and more.
  • Special effects. Dazzling fireworks and special effects like smoke and fog are common parts of every holiday show, it seems. Liquid nitrogen, liquid carbon dioxide, and propane can all be used to create smoke, fog, or haze.
  • Food preservation. What would a holiday be without food? Thanks to industrial gases like nitrogen, oxygen, and carbon dioxide food can be safely preserved, frozen, stored, and chilled allowing it to making the long trek from farm to tables in Brampton. Oxygen is also used in fish farming to aerate tanks and CO2 is sometimes pumped into greenhouses to boost plant production.
  • Bringing people together. Without portable oxygen tanks, many people would be unable to leave their homes or hospital beds to enjoy these events and time spent with friends and family.
