Oxygen is More Interesting Than You May Think

admin September 29, 2015 No Comments

Most people know that without oxygen, no living thing on our planet would exist, but there is much more to oxygen than simply the most important part of the air we breathe. Oxygen itself is a colorless, odorless gas that occupies the eight space on the periodic table, is a diatomic nonmetal, and was discovered around 1773 by Carl Wilhelm Scheele in Sweden and named in 1777 for the Greek words oxys, or acid and -genes for producer. However, it was determined its name was not quite accurate as it originally came from the belief that all acids needed oxygen in their makeup. While hydrogen and helium are the most abundant elements in our universe, oxygen comes in third, but without it, we would cease to exist. Below are some more interesting facts about oxygen you may or may not know.

Oxygen is Much More Than Just Air
– The air we breathe is made up of approximately 21 percent oxygen, 78 percent nitrogen with the remaining one percent made up of various gases.

– Oxygen itself is not flammable; however, it does provide fuel to support the combustion process. This is why any fire will burn better if it has good ventilation.

– Almost two-thirds of the weight of living things is oxygen. This is because living things are made up mostly of water and nearly 89 percent of water is made up of oxygen.

– Oxygen is replenished by green plants through a process called photosynthesis, without them, our air would contain nearly zero oxygen.

photosynthesis creates oxygen
– There are five main elements that make up the Earth’s crust and nearly half of its weight comes from oxygen. The other half is made up of silicon, aluminum, iron, and calcium.

– Without oxygen, we would not have the phenomena of the Northern and Southern Lights. The green and dark red coloring is caused when oxygen molecules are split, which causes them to lose energy and emit photons that produce the stunning colors.

– When you hyperventilate, it is not caused by too much oxygen, it is caused by the loss of carbon dioxide, the by-product of oxygen produced in our lungs. It is the disruption in this balance that causes you to feel faint, nauseous, and eventually faint. By breathing into a paper bag, you can recycle the carbon dioxide you exhale and restore your body’s balance.

– Oxygen used for medical and industrial use is obtained by super-freezing liquefied air and capturing the oxygen gas that is released. Oxygen in its liquid form is not clear it is actually pale blue.

NASA has studied oxygen and can trace its long history back nearly 2.5 billion years, but have yet to determine exactly why it became a predominant part of our atmosphere. It is thought that photosynthesizing organisms, like green plants, flourished after geologic changes in the Earth, thus increasing the amount of oxygen produced in the air.

While the fact that we require oxygen is simple, there is so much more too this odorless, colorless substance. Aside from being a requirement for living things to exist, oxygen has a number of uses in the manufacturing of glass, steel and chemicals as well as a supplemental gas for welding. The most common use of oxygen is in the medical community. Supplemental oxygen is used to treat patients who suffer from a variety of lung disorders to help maintain a healthier level of oxygen in their blood and is packaged for both hospital and home use. There is no doubt that although we cannot see, smell or feel oxygen, it is one of the most important elements in the universe.

Meet the World’s Largest Welding Tool

While welding is an integral part of how many things are made on Earth, the need for this technology goes far beyond your local auto repair shop or construction site. Imagine what it takes to accommodate the welding needs of spacecraft that is subjected to both high heat, large debris and dangerous voids in the atmosphere that is destined to venture farther into space than we have ever reached. When NASA began development of the new Space Launch System (SLS) rocket, they also needed to create equipment that was capable of building it. This led to the development and construction of the world’s largest welding tool, the Vertical Assembly Center.

The Space Launch System (SLS) rocket will be used for deep space mission to asteroids and eventually sent to Mars. To make this possible, NASA has designed it to be the most powerful, and one of the largest space vessels they have ever built. Standing over 200 feet tall with a diameter of nearly 28 feet, the rocket will hold large amounts of both liquid hydrogen and liquid oxygen, enough to supply its four RS-25 rockets on lengthy missions. It is also designed to be able to carry astronauts to the Orion space station and in the future, begin to explore destinations much further into our solar system such as Mars.

Surrounding all this precious cargo is a structure built from 2219 aluminum alloy. Part of the wrought-aluminum family, 2219 aluminum alloy is composed of aluminum, copper, iron, manganese, zinc, and trace levels of other metals. This combination creates an aluminum that is not just incredibly strong, but extremely resistant to warping, stretching, or bending under extreme conditions, including high heat. While this is the ideal material to use for spacecraft, its resistance to high heat also makes it difficult to weld. Considering this, NASA began building its special Vertical Assembly Center equipped with a special welding tool kit that is capable of helping construct our future spacecraft.Watch movie online The Transporter Refueled (2015)

NASA employs two different types of welding for aerospace applications using 2219 aluminum alloy. The first is Gas Tungsten Arc welding done in a flat position that uses a high purity helium gas shield to provide deep welds without contamination or oxidation. The second, more advanced type of is Variable Polarity Plasma Arc Welding. It offers the high-heating capacity needed to bond 2219 aluminum alloy, can be performed in a vertical position, and needs no shielding gas. The Vertical Assembly Center employs this welding technology, and with the help of a computer, and is being used to weld the core stage of the SLS rocket. Standing 170-feet tall and 78-feet wide it is currently the largest spacecraft welding tool in the world. While this is the just the first project it is being used for, its state-of-the-art technology will be able to accommodate many future spacecraft builds.

The 3 Most Common Types of Welding and When to Use Them

admin August 13, 2015 3 Comments

Not all welding is created equal and knowing the 3 most common types and when to use them is very important. Welding has come a long way from the days of the first blacksmiths heating metal in a huge forge and then beating it with hammers on an anvil to create welds. Today, technology has improved so much that the heat of a forge can be focused into a smaller, more defined area that makes repairing and creating anything metal much quicker and easier. The following are the 3 most common types of welding, TIG, Stick, and MIG, and the best situations to use them.

The Versatility of TIG WeldingCriminal 2016 live streaming film

TIG, tungsten inert gas, welding is a very common type of welding and can be used to weld nearly any type of metal. It uses a tungsten electrode that can withstand an extremely high heat to produce welds. It works by creating an electric arc between the electrode and the surface being welded that melts the metal to its melting point. It also uses some type of inert gas such as helium or argon to protect the area being welded from atmospheric contamination.Watch Full Movie Online Streaming Online and Download

TIG welding can be done on carbon and alloy steel such as bike frames, exhaust pipes, and roll cages for race cars or off-road vehicles, stainless steel, aluminum alloys, nickel, magnesium alloys, titanium alloys, copper and cobalt alloys and even pot metal blends. While TIG welding is the most versatile, it does require the surface to be clean and takes longer than most other types of welding to achieve the desired results.

The Ease of Stick Welding

Stick, also called shielded metal arc, is also a very common type of welding and works well on a variety of metals and can be performed almost anywhere. Stick welding works by passing an electric current through the “stick” and creating an arc at the point of contact. Stick welding can produce a working temperature of up to 7,000 degrees Fahrenheit. It can be used to weld carbon steel, all types of alloy steel, cast, and ductile iron. While it can be used on other metals such as copper and aluminum, those materials are typically handled with other welding techniques. Stick welding is predominately used in the repair and maintenance industries as well as in the construction of steel structures and industrial fabrication.

Stick welding can be performed almost anywhere and is not affected by rain, wind or other poor weather conditions. It is also the simplest type of welding to learn to do. The equipment and supplies needed are also relatively inexpensive making it a great option for a smaller shop or those who move from construction site to construction site. As long as you have a place to plug-in, stick welding can be done nearly anywhere.

MIG Welding Makes Big Jobs Easier

MIG, metal inert gas, welding uses a continuous feed wire as an electrode and an inert or semi-inert gas to protect the area being worked on from contamination. MIG welding is quicker than other forms of welding due to the use of a continuous feed electrode wire that creates a constant arc between the welder and the metal surface being worked on. MIG welding can be used for small or large jobs and requires slightly more experience than other welding types due to its semi-automatic to automatic functioning and potentially complicated welding equipment.

MIG welding can be used on a variety of metals and allows the user to create long, clean welds that make getting larger jobs done faster. It also allows more working time because stopping to change electrodes is eliminated. While it is great for spot and tack welds, it can be used on nearly any type of construction and repair project. MIG welding is not suggested in windy or rainy conditions however due to the possibility of contaminating the area being worked.
