In the article where we wrote about laser welders, we promised you an article about how a classic welder, i.e. a welding inverter, works. It is still not a technology that is no longer usable, it is still a great benefit for production and there are still new welders who are happy to learn something.
So we are still talking about the basic purpose of welding, which is to connect two elements together with a solid, mainly non-dismantling joint. Here too, we dare to say that welders most often work with metal. Other materials can also be processed, but today we will only focus on the principle of operation of the welding machine. So are you asking us the question, how does the welding machine work?
The basics of welding, and for some later even art, because the results are often fascinating.
Welding in general, regardless of the specific type of welder, is still the process of joining two materials. Unlike soldering, which uses a lower melting point binder, welding joins parts directly together, although sometimes with the use of filler metal. This is important to mention in comparison to laser welding, if you haven’t read our article about it. However, even with the use of filler metal, welding still leads in the way of joining parts that are then permanently joined.
Let’s take a moment to look at the history of welding. Here we are talking about the Bronze Age, when metals were heated and shaped. With the advent of the Industrial Revolution, welding techniques improved considerably and today include advanced methods such as arc and laser welding.
The most commonly used welding techniques are:
Already mentioned Soldering: The strength of soldered joints is generally low and the heat resistance is poor. Lap joints are often used, which increases the consumption of basic materials and the weight of the structure. The overall heating requires solder.
- Flame welding: Uses a mixture of flammable gas such as acetylene and oxygen to create a high-temperature flame.
- Arc welding: Uses an electric arc to melt the material. Includes methods such as MMA, MIG/MAG, and TIG/WIG. The welder has high labor intensity and poor working conditions. Low production efficiency, welding wire needs to be replaced frequently. High skill requirements. The welder’s working skills and experience directly affect the quality of the product.
- TIG welding: As mentioned above, it uses a high-energy laser beam and is popular in industrial applications. Unfortunately, the welding quality is often poor here, because this welding technique is difficult to operate and there are also high protection requirements.
We will mention again that laser welding is also among the above, and no matter what welding technique we are talking about, the technique always has one thing in common. Welding offers a durable connection and is very versatile. Thanks to these properties, it is indispensable in all manufacturing sectors. After all, just imagine a bridge connecting two cities, or anything else. Without welding, such structures would not be possible. Welding is also key in the repair and maintenance of machines, which ensures their long service life and safety. So, whether a company manufactures or repairs something, welding is very often used.
