Knowledge is Power! That’s the age-old saying. And we are firm believers that the more you learn the better your quality of life will be. It has been proven that we, as a species, crave education. We thirst for knowledge. And it is this drive within us that has led our species to advance to the staggerings hights we have!
And while there are some out there that would like to think they know everything, we know that there is always more to learn! And, if you have clicked this article, it seems you think like us. So, join us as we take a look at a few topics that you might be curious about, but never thought to look into. And together we will discover How It Works!
Everyone has seen the image of the Hot-Rod greasers welding their rides. Or watched as Iron Man welds an arc-reactor onto an underwater pipe in the Avengers. But how exactly does Welding actually work? How do two completely separate sections of metal suddenly become one solid mass? And is it possible to join two pieces of metal without a welder?
Let’s start with the basics. What is Welding?
Welding is the process of using intense streams of heat to melt metals and fuse them together. Seems simple right? But it has a lot more complexity to it than it first seems.
In movies and TV shows you always see someone go at a slab of metal with a welding torch and instantly connect it to something else. But, in actuality, there is a third key component needed for this. A welding rod. This rod is made of a different kind of metal and is melted down across a specialized strip of wire, held between the two pieces of metal. The melted rod cools around the wire and between the metal, thus connecting it into a solid mass. It is the electrode wire that gives welded seems that rigged appearance.
Welding is a powerful process that can strengthen structures immensely. Once the sections of metal are joined together they become stronger, more resilient. This is great for large scale construction. Welded metal also provides more security. A welded structure is often a sealed unit. This is great for cars and other objects that have delicate internal mechanisms in need of protection.
But welding isn’t the only way of attaching metal together, it is simply the only method that can turn the separate pieces into one object. Other methods include using rivets, which are simply massive bolts that are injected through the metal by a powerful machine. The force of the rivet entering is so strong it creates a perfectly tight seal. Removing an object that has been riveted is no easy task.
Another common method is to use industrial hot glue. This glue is designed to melt when superheated and them reform between the sheets of metal. This glue isn’t like the glue you can buy at a craft store. This glue is essentially unbreakable.
Welding is an extremely cool, and physically hot process! Visually it is very fascinating. Watching metal melt and form into one is incredible. But it is also very dangerous and should only be carried out by trained professionals who know exactly what they are doing.
Welding torches and arc-welders reach staggering heats. The melting point of most metals is anywhere between 400 degrees to 900 degrees. Those heats would cause irreparable damage to a human body. So stay safe and do not try welding at home!
