Argon and helium gas welding
Why argon and helium gas welding is important When welding, particularly arc welding, it is key that your use some form of shielding or welding gas. Argon and helium gas welding provides more suitable conditions for the welding arc by protecting it from the damaging effects of the surrounding air. If a welding arc comes into contact with heated metal, the oxygen will begin to oxidise the metal. Additionally, nitrogen or moisture in the air might cause the welding to become porous or brittle. All of these factors are undesirable when creating strong, durable welding joints. The presence of welding gas thus improves the surface appearance and geometry of welds, while ensuring arc stability and increased metal transfer. Welding gases also burn off alloying elements and oxide formation on the bead surface. By using welding gas you can increase your overall welding speed. Should I be welding with argon gas or helium gas? The two most common forms of shielding gas are argon and helium (or a mixture of the two). Argon is a naturally occurring non-flammable and non-toxic gas that is colourless, odourless and chemically inert. Argon is particularly effective in protecting weld sites from detrimental atmospheric influences, such as oxygen, nitrogen, and water particles. As such, Argon is commonly used in welding and other high-temperature industrial processes, which often cause non-reactive materials to become reactive. Argon is the best gas for shielding tungsten arc welding with an alternating current (AC). It provides extremely stable and quick starting arcs as well as cleaner welds. Argon gas is also the most commonly used shielding gas for welding aluminium. Pure helium, on the other hand, is used more commonly in direct current electrode negative (DCEN) gas tungsten arc machine welding. Pure helium provides high heats which result in fast welding speeds and deeply penetrating welds. This is particularly useful when creating full penetration butt welds, which are only welded from one side. Argon and helium mixtures also produce high [...]
Balloon gas cylinder – 4 reasons to get your own Helium Tank
Always be ready to party with your own balloon gas cylinder Everyone has important milestones in their life that they want to celebrate with a party. Birthdays, weddings, christenings, anniversaries, the list goes on. Having fun with family and friends is great, but the preparation for each event can be tiring. This is never more true than when you have a big family, because some sort of celebration is always on the horizon. Instead of manually blowing up balloons for every party you’re going to host this year, why not invest in your own balloon gas cylinder and balloon inflation device? Here are four reasons you should: 1. It’s easier to use a balloon gas cylinder Why make life harder for yourself? Blowing up balloons is difficult and tiring, sometimes even painful. When you have a packet of 30 in front of you to get through, it’s tempting to forget about them altogether. However, a helium balloon gas cylinder is extremely easy to use. We also provide the helium regulator, or inflation device which connects to the cylinder directly and enables you to inflate the balloons safely. This makes the whole process quick and easy, giving you more time to do other jobs, to get ready for the party. 2. Using balloon gas produces big, beautiful balloons You’re going to lots of effort to make sure your friend’s surprise birthday party is the best it can be. However struggling to blow up balloons and giving up before they reach their full size may save time and energy, but they never look as good. Using a helium balloon gas cylinder will enable you to produce big, full-sized balloons every time, making your party decorations look professional. 3. Create your own unique floating balloon decorations When you blow up balloons with an air inflator or your mouth they don’t float on water. Helium filled balloons float in the air or water for around 10 hours which lets you create eye-catching decorations for your party [...]
Rent free welding gas for all your DIY needs
Do you find that obtaining the gas you want for high calibre home welding is a challenge? Perhaps you’re struggling to find top quality gases in the quantities you need. In these circumstances, why not opt for the rent free welding gas we provide? Rather than having to drive miles to source the gas you’re after, only to find that the size or type you want isn’t in stock, why not use our hassle free, economical service to obtain the gas you need to get the job done properly? Argon, oxygen and carbon dioxide In addition to selling these gases separately, we also stock an argon/oxygen/carbon dioxide 5:2 mixture. Ideal for MIG (metal inert gas) welding, we have over 30,000 cylinders in the market at the moment. Oxygen is well-known to improve the arc and reduce metal tension, giving better results than simply using argon on its own. For TIG welding on stainless steel or aluminium, we recommend pure argon to get the right outcomes. Range of different sizes to meet your needs We know that if you’ve only got a small welding job to do, there’s no point in buying an enormous cylinder of gas. Our smallest size, C, can usually be dispatched to you using Australia mail – no fuss and no rental, and it’ll be with you quickly. For larger sizes (D, E and G), we can provide delivery within 25km of the CBD in Sydney, Brisbane, Adelaide and Melbourne. We supply gas regulators and other equipment If you haven’t got all the necessary equipment to get your welding job completed successfully, we can help. We stock a wide range of welding essentials which we are happy to supply if needed and if we don’t have the goods we will direct you to one of our partners who will have it. If we deliver in your area, we will drop them off at the same time as your gas, saving you time and [...]
