Helium Welding Applications, Sources, and World Supply
Helium has been a staple in many forms of welding for decades. It is an excellent shield gas for applications that require high heat input because of its effective thermal conductivity, and for high production environments where a higher travel speed is required. Helium is also well suited for welding thick material, because of its deep penetration profile.
Most often, it is mixed with other gases to create a welding gas that exhibits the best characteristics of each component gas. It is often used in welding non-ferrous metals like Titanium, Aluminum, and Magnesium, and stainless steel. These are some of the same applications in which Argon is also used, but Helium needs a higher flow rate, and is significantly more expensive than Argon. Why is that?
Helium is a by-product of refining natural gas. In the 1950’s, the U.S. government set up a refinery, specifically for the purpose of collecting it, which it believed would play a vital role in the expansion of space exploration. The field where they built the refinery in Amarillo, Texas, turned out to be very rich in Helium, and in more recent years, the U.S. Federal Helium Reserve account for about 30% of the world’s accessible supply. It is estimated that that reserve may run out of recoverable Helium in the next three to five years.
There are about a dozen other sites worldwide, which are known to have helium deposits large enough to make it worthwhile to develop them. A refinery opened in Saskatchewan, Canada in 2014 and Qatar opened a new refinery in 2013, but other deposits have not yet been developed.
The advent of superconductors, like those used in MRI machines, have also increased demand and, subsequently, prices. Helium can be cooled to four degrees Kelvin, and used to absorb the massive heat generated by the magnet and superconductor wire as they create the magnetic field. These applications are currently demanding about 20% of the annual world supply. The remainder is used across a variety of other applications ranging from lasers and coolants for reactors and space ships, scuba diving tanks, and weather and even party balloons.
Is It Time To Worry?
The world will not be running out any time soon. There may be some fluctuations in pricing and availability as the Texas deposit winds down and other sources around the world are developed. Keep calm and weld on.

Nitrogen Gas Keeps Food Safe And Appealing
Nitrogen gas can be safely used to package all kinds of foods for long-term storage, shipping, and protect foods from crushing. This process is called Modified Atmosphere Packaging (MAP), and can use Nitrogen, Argon, Carbon Dioxide, or Carbon Monoxide, depending on what food is being packaged. Food gases differ from Industrial gases with respect to the degree of purity and the two should not be interchanged. For some foods, Nitrogen packing is a matter of visual appeal, but for others, it is a critical matter to ensure usability.
- Coffee Packaging – Coffee goes stale very quickly when it is left exposed to oxygen. One of the things that make coffee so appealing is the volatile oils which produce that heavenly aroma. Once those oils are subjected to ambient air, though, they weaken and change, and the coffee loses not only the power of its signature scent, but the fullness of its flavour, as well.
- High Moisture And High Fat Foods – To keep food looking and staying fresh for longer periods of time, a Gas Mix containing Nitrogen and CO2 is used. The CO2 prevents bacterial growth in foods, Nitrogen keeps high fat foods more visually appealing. A variety of combinations of the two gases are used in for many vegetable, meat and seafood packing purposes.
- Dried Snacks – Pure 100% Nitrogen gas is used in packaging dried snacks to replace Oxygen in the packing and keep the snacks fresher, longer.
- Pressurized Protection – Have you ever wondered why your favourite potato chips arrive in a puffy bag? A Nitrogen gas flush is used in the packaging of delicate foods like potato chips and crackers. This allows manufacturers to ship the food in a “pillow” to prevent breakage, and reduce the risk of Oxygen making the food stale.
- Stalling Bacterial Growth – Aerobic bacteria, like some strains of Bacillus, need Oxygen to survive. When a food package is flushed with Nitrogen, the Oxygen is driven out, which will prevent the bacteria from growing as long as the package remains sealed.

Propane Suppliers: Why Bigger Is Not Always Better
If your business is running forklifts, chances are you need a propane supplier. Maybe you have been ordering from one of the gas giants. How responsive are they to your company’s needs? Most likely, you have found that you are an account number and a monthly check to them, and that it is you who has to bend to their limitations, instead of the supplier accommodating you.
Your Success Is Our Success
At Josef Gas, we recognize that, at the end of the day, we make our living by giving our customers what they need, when they need it. We are a mid-sized company with our own fleet of cylinder and bulk gas delivery trucks, operating throughout the Greater Toronto Area. We do not have a regional dispatch center running thousands of trucks, like many unbreakable lines of ants. We have field representatives driving our delivery trucks, and because we are not trying to check off some corporate metrics on a chart, those representatives are able to offer our customers flexible options. If you need an extra refill in between your regular deliveries, we can do that. If you want to change your schedule, we will do it now, and not in two weeks.
We have been working with the same gas suppliers for 40 years. We have long-standing relationships and long-term contracts that allow us to supply our customers with propane at the best prices.
Josef Gas saves its customers even more money by not charging the endless string of fees that other propane suppliers charge. Say goodbye to the Environment charges, Hazmat charges, and Barcode charges. We will bill you for the product you receive and for delivery: nothing more.
