Construction

Any construction involves work with metal structures, in particular - they can be bound in strong elements. This compound is resistant to mechanical impacts and other damages, and for such types of work the welding is applied.

Among all technologies of combining the elements of metal structures the manual arc welding remains the undisputed leader. It allows obtaining permanent connections. If builders buy welding electrodes suitable for the particular steel brand, so the weld fails get characteristics that are close to the parameters of the base metal structures.

Currently for the welding of constructions the different welding equipment for manual and automatic welding is used. Equipment for manual metal arc (inverter welding rectifiers, generators, transformers) and TIG MMA welding (welding machines with gas burners) are indispensable for high-rise and installation works, repairing of building structures.

Equipment for automated welding (welding semi-manual machines and automatic machines) is used primarily in the manufacturing of solid sheet metal structures - bridge beams, solid columns, crane runways and other building structures. The individual assembly steps may be carried out by manual arc welding, for example, welding ribs to a welding beam. Consumable in automated welding is welding wire, which has a higher efficiency compared with MMA electrodes (up to 85-95 percent for automated welding methods and about 65 percent for manual welding).

In the production of engineering structures the requirements for welding precision and strength of welded joints are increased. Usually, this welding is applying with the help of special welding machines (production lines) for the contact or automatic submerged arc welding. In some cases, sealing of joints of numerous shorts are performed with the help on manual or semi-manual arc welding.
