The use of welding in the construction of reservoirs



For the construction of high-capacity metal tanks used welding technologies, including manual arc welding. It requires electrodes stamps depend on the composition and thickness of the metal parts to be joined. While the primary role in the assembly take automated technology and mechanized welding, but for some operations use the manual method is the only possible.

During the construction of the assembly is carried tanks of individual sheets, blocks or roll method. When Mounted Roll method in industrial conditions on special welding machines manufactured wall and bottom. They are delivered in rolls, and combined unfolded on site by welding. In this case, the mounting elements and perform manual tack welding. For her, using electrodes of a certain brand. It corresponds to the assembly seam welding materials, as potholders then become part of it. Roll method is the most progressive, since it provides the best quality of welded joints made in the factory, and increases the speed of installation. His weaknesses - is the complexity of transportation and installation of large rolls using special techniques and special lifting equipment.

With sheet or block method as normative construction documents is recommended to use automatic welding technology. However, in this case, the proportion of manual method, for which need high quality electrodes strong > , may be significant. For example, manual arc welding is used in the installation of tanks at existing facilities in terms of lack of space. At the same time produce a sheet assembly and the scope of work is insufficient to operate the welding machine.

To ensure a quality weld requires its continuous strip during one cycle. To join parts of structures made of carbon and lightly alloyed steels are among the best standard electrodes ANO-21 production "SpetsElektrod." They differ easy ignition, combustion stability, and allow you to get a quality weld, even a novice welder.

The particular complexity of different assembly of spherical tanks. If it is made of enlarged flap blocks required gasket ceiling joints. Run it allow Electrodes Standard ANO -21, which are used for any position and direction of the process of doing.
Thus, manual welding technology is still relevant in the construction of metal reservoirs.
