1. Introduction Oxy Acetylene welding is one of many kinds of welding. The fundamental process is to joint two parts of metal becoming one part by a high temperature. The thermal flame is created by using the mixing of oxygen and acetylene gas (anthonycastronovo, nd) 2. Compatible materials are used for oxy acetylene welding: - Mild steel Aluminum, stainless steel, copper and brass. However these things are suitable for brazing process (anthonycastronovo, nd) 3.

Two benefits of nuclear fission technology for society are that significantly fewer amounts of greenhouses gases are being released into the atmosphere, compared to fossil fuels. This results in a slowed rate of pollution and global warming. Another benefit is that power created through nuclear fission is immense and is able to meet the demands of large and industrial cities as well as the suburban towns too. Also the energy is quick to create too, which means that immense amount of energy can…

Welding is the most common way to join two or more pieces of metal together. There are many types of welding like explosion welding, shielded metal arc welding, gas metal arc welding. Explosion welding and that’s when you take gunpowder and two pieces of metal. Then you ignite it and it goes kaboom and then the two metals combine to make a weld and that’s how explosion welding is done. I have always found explosion welding very fun and cool because of all the things that go into it. I have…

Furthermore, it is vital for life to exist on earth, from the grass lions, bears, and humans trample on every day, to the fish and plankton in the ocean. Without potassium, the ninetieth element on the periodic table with chemical symbol “K,” life would be immensely different today, notwithstanding any in the first place. Potassium functions a significant role in…

Environmental disaster, radioactive zombies, and a barren nuclear wasteland. All three are common first thoughts when it comes to thinking about nuclear energy. Why? For starters, because our culture loves to focus on the horror stories like Chernobyl and the possibility of a nuclear meltdown. Fortunately, no matter which way you look at it, none of the hype is justified. Nuclear energy is one of the safest, most environmentally friendly, and most efficient forms of energy production that we…

global warming? Absolutely not, the answer is simply reducing the fossil fuel usage by investing more in renewable energy sources especially Wind and Hydroelectric instead of investing in burning more coals to store it underground. Fig. 5 shows that wind is at least $400 millions cheaper than coal over the next 25 years, and need to mention, 26% of North Dakota’s power is generated by wind at 2.5 cents per…
