Welding (welding works) - the most often used technology of one-piece connection of details. This technology is used in various industries: construction, automotive industry, shipbuilding, etc., including in metal working. One of the main advantages of welding is the possibility of compound of the materials differing in physical and mechanical properties.
Allocate three main types of welding works: mechanical, thermal and thermomechanical.
At mechanical type of welding works welding happens due to the mechanical energy and pressure connecting materials and is applied to cladding of metal surfaces by alien materials. Ultrasonic welding of metals, cold welding belong to mechanical type of welding works welding by explosion.
Arc welding, argonodugovy welding, gas-plasma, laser, thermite, electron beam and some other types belongs to thermal welding works. All these types are united by melting with use of thermal energy. Argonodugovy welding, was widely adopted. The main advantage of argonodugovy welding is the high level of quality of welded seams. Its reliability is higher than the level of reliability of the soldering as seams cook and become a whole with a product. Argonodugovy welding, differs in use of not melting electrode in the environment of protective gas that allows to weld various materials: carbonaceous became, alloyed became, the titan, aluminum alloys. Welding works as argon provide tightness and durability of a finished product. In this regard, argonny welding gives the chance to increase the term of operation of finished goods. In LLC Research Center TLLTD argonodugovy welding is widely applied to welding of aluminum and its alloys.
Contact welding, spot welding, butt welding, relief welding, diffusion, forge, welding by high-frequency currents and some other types belong to a thermomechanical type of welding works. All these types are united by use of pressure, in addition to thermal energy. In LLC Research Center TLLTD spot welding is applied. At spot welding of a detail are clamped in special welding pincers. After that between them big current which warms metal of details in the place of their contact up to the melting temperatures begins to proceed. Then current is disconnected and "pro-forging" due to compression of pincers is carried out. Metal crystallizes and welded connection is formed.
In our company all works on welding are performed by high quality experts on the modern equipment. Aluminum welding, use of argonodugovy welding, application of spot welding - priority activities of LLC Research Center TLLTD.
