Such designs are called the svarnolitymi or stamped and are widely used in aircraft, automotive, car building and other areas. The use of such structures provides a saving of metal and labor. By welding details can be made of metal, held a variety of pre-processing, for example, welded rolled profiles with stamped, forged or cast blanks. You can weld dissimilar metals: stainless steel with carbon, copper and steel, etc. In the manufacture of complex-shaped structures using welding instead of forging and casting gives a big economic impact. For example, labor productivity in manufacture of welded structures is 2 times higher than the casting and forging and stamping, and working conditions are much better.
Capital investment per ton of welded structures are 1.5-2 times lower in cost and 1.3-1.6 times lower than in the foundry production. By reducing weight, increasing reliability and durability of products. 4.Udeshevlenie technological equipment. The welding equipment is relatively easy, relatively cheap and very high. It reduces the capital costs of metalworking plants and accelerate their entry into force. 5. Facilitating the integrated mechanization of mass production of the same type of welded products, the ability to create mass production with 100% automation and mechanization of the production cycle, which dramatically increases the removal of industrial output per unit area of the shop.
6. The possibility of broad primeneniyav welded constructions progressive modern types of materials: high strength, lightweight curved profile, multi-layer sheet steel, light alloys, high purity metals, etc. 7. Facilitating the production of components and microminiature parts in the manufacture of certain types of products – semiconductors, etc. 8. The possibility of widespread use of welding, surfacing and cutting the repair where the metal treatments provide a quick and cost-effective to restore worn-out, the failed equipment and damaged facilities. 9. Tightness and reliability of welded joints. 10. Reducing industrial noise and improve working conditions in shops.
