More than half of all modern buildings and structures are built on the basis of monolithic methods. Its demand is due to the fact that with minimal temporary costs it is possible to obtain finished construction products of almost any form and configuration. The fantasy of the architect is limited only to the choice of formwork – the form in which the finished concrete mixture is filled. Previously, a steel frame is placed in the design – we are talking about the use of concrete at the facility, but reinforced concrete. The advantages of this composite include its high mechanical strength, a long -term operational resource. The concrete base is responsible for the strength of the material for compression, the reinforcement – for stretching. Task number one for builders is to choose a technology for mating of metal structures. Buildings on the reinforced concrete frame are often erected in seismic zones – the steel elements of the skeleton in this case should be connected into a single monolith. In 9 cases out of 10, manual electric arc welding is used at the facilities – a universal technique that has proved its versatility and reliability for a long time. The receipt of the seam is due to the melting and subsequent cooling of the surface – to transmit the thermal impulse of the arc, welding electrodes are necessary. What are we talking about? This is the name of the rods of various nature, which act not only by high -temperature conductors, but they themselves are directly involved in the receipt of the seam. The constituent elements of the butt connection is the metal of both the main part and the electrodes of welding. The popularity of the methodology is explained by the fact that after crystallization, the joint is no different in strength from the main material, retains the ability to perceive colossal dynamic and static loads. On hundreds of domestic construction facilities, the Electrodes of the MP-3C welding brands with a coating of route type. The rods are able to ensure a seam with high user criteria, differ in good separation of slag, small spraying of the metal. Welding electrodes MP-3C are suitable for obtaining conjugation of roller, butt angular, taurus and end types.
