The welding machine is a machine that is used for fixing materials. The union of these is achieved thanks to the melting of both materials or with a filler material that , while melting, is placed between the pieces to be welded and when it cools it becomes a fixed and resistant union.
The art of welding is a trade that has many centuries of history, it could be said that even for millennia. So if we stop to think, operating welding machines is one of those jobs that never goes out of style.
The process of joining two metallic bodies after subjecting them to high temperatures has been established since ancient times. Some archaeologists place the appearance of welding in India, around the year 310 BC. C. and you can imagine writings from the time of the Romans that speak of this method of fusion.
It was in the second half of the 19th century when the technique of fusion welding using electricity, the true ancestor of modern welders, became patent in England .
But welding is not just a technical skill that can become a career path for many people. It is also a skill that helps to undertake small domestic jobs of metal utensils or, simply, entertainment. In any case, for both professionals and non-professionals, the use of protective accessories is recommended to avoid any damage during welding, such as protective face masks, gloves or helmets.
So if you would like to learn this artisan art, you may be interested in learning to weld with our specialized course. You will learn the different techniques used for each type of job. Of course, a very interesting course if you are looking to know more about this way of working with metal.
You can find a wide variety of welding machines on the market
At present, there are many classes of welding machines:
Arc welding
One of the most famous methods is arc welding. This machine uses electricity to melt metal through heat. This type of welding is very dangerous and requires a lot of preparation work. Metal rods, called electrodes, form arcs at their ends.
These electrodes have a thickness of 1.6 to 2.5 mm. Poor performance can cause serious burns and other accidents. Therefore, it is recommended to use these machines for welding.
To avoid setbacks, it is necessary to use a protective screen, protective gloves, green glass protective glasses and suitable clothing in this type of welding to prevent rapid combustion. We can also find several sub-types of arc welding machines:
– Manual metal arc welding machine. This machine manages to weld the pieces using steel electrodes.
– Metal arc gas welding machine. He manages to weld the pieces using an inert gas, such as nitrogen.
– Flux cored arc welding machine. This machine works by means of a system in which the electrode produces a shielding gas.
– Tungsten gas arc welding machine. In this type of machine, the electrode is made with this material.
– SAW or submerged arc welding machines. The fundamental characteristic of these machines is that they use a granulated material that protects the arch. This material can be a calcium oxide, manganese oxide or calcium fluoride, among other materials.
Tin solder
Another type of soldering iron that you can find is the tin soldering iron . This type of tool achieves welding by melting the tin through the heat generated by electrical energy , which is transmitted through a metal tip. It is tremendously useful for repairing small appliances and is widely used in the electronics arena.
Currently, you can find various types of tin soldering iron on the market. Depending on their power we have them from 12 to 220 V. The most common is the resistance welder ,which is made up of a copper tip and an insulated handle. You can also find the so-called instant welder, which is characterized by its gun shape. It is very useful in the welding of minor elements.
Gas welding
The difference between these machines is that they have a flashlight. The gas is kept in a jar or identical pot, and the tube acts as a link between the gas jar and the lamp. These welding machines are normally used to join alloy elements such as aluminum or copper, and are broadly used in the pipe industry.
Laser welding
You can also identify welders who work lasers. These machines can play welding by adding a lot of heat to the area to be welded, which is very useful for welders or small areas.
Inverter welding
There is no doubt that the most advanced welding machines are inverter welding machines. Usually going, these machines are easy to remove and brighter than common welding machines. Compared with traditional welding machines, inverter welding machines are characterized by durability and welding seams. It has a wide range and realizes more energy saving. This type of welding is sometimes called digital welding.
A profession that does not go out of style
There are many reasons why it is interesting to master some of the welding machines described above. At a time when unemployment in our country is higher than 14%, mastering these machines could mean a job tomorrow.
There will always be a niche for welders in sectors such as industry, electronics, construction or certain assembly units . Even during the crisis years, welding positions have been among the most in demand in the sectors described above.
Among the industries in which welders are in high demand you can find the automobile industry, the electrical sector, the metallurgical sector, the aeronautical industry or the technology sector. The approximate average annual salary of a welder in our country at this time is around 18,000 or 20,100 euros.
Mastery of welding can also be used within art. The contemporary sculpture offers a new terrain where you can explore the possibilities of this centuries – old technique. We can cite the Russian artist Alexandra Ivleva , who has developed the bulk of her work through metal welding.
Therefore, there is always a good reason to start using welding machines , whether for work, artistic or hobbyist purposes.
