The Basic Fundamentals of Welding

We look at the basic fundamentals of welding, because what good project doesn’t require at least some welding?




There is something extremely satisfying in doing things with your hands. When you make a delicious meal yourself and eat it, it is very rewarding. When you fix something that was broken in your place, you feel pretty good about yourself. What feels best, though, is actually creating something, whether that is out of wood, metal, or anything really. This is why you must learn the basics of how to do these things at home.


In this article, we’re discussing the basic fundamentals of welding, because what good project doesn’t require at least some welding?



Understanding welding

Before you grab a piece of metal and try having your way with it, you need to first understand just what exactly welding means. It is essentially using heat and/or pressure to fuse pieces of metal together. Unfortunately, it is not just as simple as that. There are plenty of different angles to cover when it comes to welding, and you need to have a basic understanding of chemistry and metallurgy –– and even physics. In some instances you may also need to use a phase converter to convert single-phase to three-phase power in the event that you need to run industrial machinert . There is a reason why not just anyone could weld things properly; it is a highly technical craft that requires some skill and training.


Different types

Most people think that there is just one type of welding, the one you see on construction sites and in movies. Well, there are several ones actually, and each serves a different function and can be used for varying functions. There are two basic types of welding: arc and torch welding.

Arc welding is when an electrical arc is used to melt a filler metal and the materials themselves together so you could join pieces of metal. There are even different types within this one like gas metal, plasma, shielded-metal, submerged arc, and gas tungsten arc welding. As you can see on, this is a tricky kind of welding to know, and you will need some guidance on how to master this one. You should read resources and watch videos on how to wield an electrical arc to fuse metal together, and you also need to check and see what the best different protective gear in the market is.

Torch welding, on the other hand, is when the metals and welding rod are melted using an open torch, which can be quite dangerous, too, so always be prepared in terms of gear and protection. This type is often used in construction sites for maintenance and repair purposes, and by homeowners who want to fix a quick something in their garage. Oxyacetylene welding is the most popular one here, and it gives excellent accuracy as the welder can more easily control the torch and rod simultaneously.


Practical knowledge is key

Welding isn’t exactly something you could learn from a book or a video. You need to check those resources out, yes, but more importantly, you have to try for yourself until you get the hang of things. You will probably fail quite a few times at first and will rarely get it right, but with time and practice, you will be able to weld efficiently. Start with small jobs that require minimal welding where you connect metals without needing to use clamps.


How does it work?



We’ve mentioned briefly the concepts behind welding, but how does it really work? Why doesn’t the metal break or crumble under the immense heat and pressure? Well, different metals react in varying degrees to the welding process –– which is why you need to carefully research which types of welding techniques and materials go together so you don’t end up causing more damage to the metal. But generally speaking, the physics of it is the heat induces a sort of flexibility in the metal, helping it stretch and bend without breaking. This is also why welding can be quite helpful when you want to straighten out a bump or warped piece of your metal since it expands when direct heat is applied.


What can you weld?

Well, just about most metals out there. But welding is needed in several tasks and industries, so you need to know what works best for the job you have at hand. For instance, metal inert gas welding is used with steel and aluminum, which is why you’ll find it quite often in the automotive industry. Tungsten inert gas welding, on the other hand, is a slower welding process that yields excellent quality for any metal.

There is so much to learn when it comes to welding, and you will need to give yourself time to get better. Enlist help whenever you can, whether that is from professionals or even videos because you will need it early on to get better.
