Welding in construction: types, rules and technologies
Welding of details for more than a hundred years has been highly developed and today has an important place in all industries. The welding work itself is a rather energy -intensive technological process, in which, using the method of local warming up or plastic deformation, unified structures are created. Work, which is performed in one order or as part with other types of metals, is performed using thermal types of welding. The most widely used electric arc welding. Manual arc welding is considered the simplest way to connect ordinary metals.
Most studied the welding of aluminum and also its alloys – Argonoduga welding. Argon welding requires special knowledge of processing technology at the welder. Welding aluminum should occur in the environment of Argon and Helia, which is well affecting the strength of the metal. Welding technology for each product, today, can provide many welding methods. When performing the same type of operations, automatic welding is mainly used, which is used in the implementation of direct and spiral seams in pipe production and other important work. Today, arc welding remains the most popular in all areas of business.
