Today, welding is used in a wide variety of industrial construction and manufacturing industries.. During the entire existence of this kind of technology, various technologies for carrying out welding work have been invented, which have both their own advantages and disadvantages. Each of them is used in a specific situation..
The most common method of welding is manual arc welding. It is most often used when a strong connection of carbon and stainless steels is required, since this welding technology is best suited for this. The main elements of this type of equipment are the welding machine itself and the electrodes, which are coated with a special substance..
As the main disadvantage of arc welding, experts note a rather low productivity, as well as the fact that during the welding process slags are formed, which must be removed..
As for the advantages of arc-type welding, it should be noted that such equipment has a low cost, and the consumables themselves are quite affordable. The electrode allows work in a wide variety of directions, and for their use, additional fuel in the form of gas is not required.
In some cases, during arc welding, it is required to have a protective medium in the form of an inert gas, which is most often used as an electrode coated with tungsten and argon gas. This kind of welding technology is most often used to join aluminum alloys. This welding method also has a low productivity, and requires high qualifications from the welder..
Gas welding is another common method. In the process of welding in this way, metals are heated with the help of a flame from a gas combustible mixture, after which they are firmly connected. For these purposes, special equipment is used in the form of a welding machine with a gas torch, as well as a set of torches that allow the formation of flames of various directions and intensities. To weld various metals in this way, various gas mixtures must be used..
