Nowadays no construction site can do without welding process, so it is natural that welding equipment is constantly in high demand. Today there are a large number of different welding processes.
It includes the use of electrodes or graphite rods, which conduct electricity well, and the use of special welding wire, which is made by means of the hot-rolling method.
At present the market offers a very large selection of welding equipment. For example, esab welding equipment is presented both in standard versions and in the form of automated complexes.
Their welding units can be programmed according to your wishes or specific requirements. ESAB welding power sources are designed and manufactured according to the latest welding technologies. Because of this, their weight is 80 times less than the welding equipment made 70 years ago.
As the main types of welding equipment it is necessary to consider units for manual welding with electrodes of different diameters, as well as for argon arc welding with the use of non-consumable electrodes.
Welding equipment is also available, in which the electrode melts. Different fluxes are used. There are also special machines, designed for production of contact-point welding.
It is believed that DC welding rectifiers, which are equipped with fusible electrodes, are best suited for welding of non-ferrous and ferrous metals. Their main difference is the complexity of design and high cost. In the process of their use there is a loss of power, but a stable arc is formed. As a rule, this kind of equipment is intended for professional use.
For domestic applications it is best to use simpler and lighter models, such as semi-automatic welding machines with inert gas medium. This kind of welding equipment is in great demand among workers of car service companies, which perform car bodywork. In the process of installation of metal structures, it is best to use a reliable welding inverter.
