Перевод не из переводчика welding welding is a process when metal parts are joined to- ether by the applieation of heat, pressure, or a combi ation of both.the processes of welding can be divided to two main groups pressure welding, when the weld is achieved by essure and heat welding, when the weld is achieved by heat t welding is the most common welding process used day nowadays welding is used instead of bolting andveting in the construction of many types of structures, cluding bridges, buildings, and ships.it is also a basic ocess in the manufacture of machinery and in the motor d aircraft industries.it is necessary almost in all oductions where metals are used.the welding process depends greatly on the properties the metals, the purpose of their application and the ailable equipment.welding processes are classified cording to the sources of heat and pressure used: gas lding, are welding, and resistance welding.other ming processes are laser welding, and electron-beam

СВАРОЧНАЯ Сварка - это процесс, когда металлические детали соединяются с эфиром путем приложения тепла, давления или сочетания обоих. Процессы сварки можно разделить на две основные группы при сварке давлением, когда сварной шов достигается посредством эссе и тепловая сварка, когда сварной шов достигается сваркой методом тепловой сварки, является наиболее распространенным процессом сварки, используемым днем. В настоящее время сварка используется вместо болтов и сварки при строительстве многих типов конструкций, включая мосты, здания и суда. Это также основной в производстве машин и в автомобильной промышленности. Это необходимо практически во всех областях, где используются металлы. Процесс сварки во многом зависит от свойств металлов, их применения и прочного оборудования. Сварочные процессы классифицируются по источникам тепла и давления: газ, сварочная и резистивная сварка. Другие процессы процесса - лазерная сварка, а электронный пучок
