What do you generally think of when you think of copper? A lot of people will say the first thing that comes to mind is that pennies are made of copper. But maybe you didn't know that welding copper is an option, too.

You might wonder why anyone would want to weld copper. The truth is that there are many applications that have very likely affected your life. You'll probably be surprised to know about some of these.

Plus, there are many ways to weld copper. The one that the welders use depends on the specific situation. Before we get into the specifics of welding copper, what is welding in general?

What Is Welding?

Before you learn about welding copper, you might want to be sure you know exactly what welding is. In short, welding is a way to join two pieces of metal permanently. In fact, it's the only known way of making two pieces of metal into one.

There are many different welding methods. Most of the time, the process requires heat and the melting of the metals involved. However, this isn't always the case.

A weld joint, which is the intersection between the two metals that are joined together, needs to be designed in such a way that it can withstand whatever forces are going to be applied to it. Basically, the design of this joint is determined by the type of load that it's supposed to carry.

You probably use things that were created using welding techniques on a daily basis. Airplanes, cars, and skyscrapers would all likely not be around if it weren't for welding. Even smaller items within your home, such as coffee pots, were likely created using welding techniques.

There are two major categories when it comes to welding. These would be pressure welding and fusion welding.

Pressure welding

In pressure welding, the welders apply external pressure to create welded joints at temperatures below the melting point of the metal. The pressure that is being applied actually effects the metals on an atomic level.

For the process to be effective, the two pieces that you are joining together need to be very clean and have no oxides or other non-metallic substances on the surface. Welders use these techniques mostly on metals that are very ductile.

Pressure welding can involve heat. However, in most cases, it doesn't.

Fusion welding

Fusion welding techniques create welded joints using heat. Welders will heat the edges of the base metals above their melting points. They don't need to use external pressure.

Sometimes, they'll use filler metals to create a stronger weld joint. They may also use inert gases in the process to enhance the quality of the joint.

For welders to use techniques that involve fusion, the metals that they are joining need to be somewhat mutually soluble. That means you need to be able to mix them. For example, water and alcohol are mutually soluble, while water and oil aren't.

If two metals are completely mutually soluble, these will be some of the easiest ones to weld. If welders want to join two metals that have no mutual solubility, they will have to use an intermediate soluble metal. That's a metal that will have some mutual solubility with each of the two metals that the welders are trying to join together.

Now that you know certain conditions need to be met in order to weld two metals, you might be wondering: Is it even possible to weld copper? The answer is yes, it is indeed possible.

Welding copper is a practice that manufacturers use to create a variety of items. These can include crown moldings, door casings, furniture, jewelry, and much more.

When it comes to welding copper, there are a few different ways that manufacturers can go about it.

If you want to weld copper yourself, you can do so, given that you actually know what you're doing. If you don't, this could be a very dangerous project for you. It would definitely be worthwhile to learn this skill since copper has many home improvement applications.

Before you undertake this project, make sure you know everything about how to do it properly. Learn about the copper alloys you're using, and try the process in small pieces before you try your hand at the final project.

Most importantly, make sure you're completely safe. You're dealing with some extremely high temperatures here, and you want to make sure to protect yourself completely.

1. GET EVERYTHING TOGETHER

2. CLEAN EVERYTHING

3. CUTTING THE METAL

4. POSITION MATTERS

You Can't Wait to Weld Now, Right?

Now that you know more about the welding process in general and welding copper specifically, you know just how fascinating the processes are. Because of all of the applications of welding, you also know just how important they are. Your life literally wouldn't be the same if it weren't for welding.

If you decide to try welding copper yourself, make sure that you take all the proper precautions. Remember that it involves a lot of heat. The process may be fascinating, but it can also be quite dangerous.

Welding copper can be very useful and likely played a part in the making of many of the things that you use on a fairly regular basis. And it always helps to have a better understanding of how things are made.
