Изобретение отиоситс к области машиностроени , в частности к способам контактной точечной сварки соединений преимущественно тугоплавких металлов со сталью.The invention relates to the field of mechanical engineering, in particular to the methods of contact spot welding of joints of mainly refractory metals with steel.
Известен способ контактной точечной сварки , при котором сжимают соедин емые детали , пропускают сварочный ток, выключают ток и снимают усилие сжати 1.A method of resistance spot welding is known, in which the joining parts are compressed, the welding current is passed, the current is switched off, and the compression force 1 is removed.
Однако этот способ не позвол ет получить качественного соединени в св зи с тем, что ток выключаетс до момента сн ти сварочного давлени , в результате чего происходит растрескивание вольфрамовых контактов, потому что соедин емые металлы обладают разными теплофизическими свойствами.However, this method does not allow to obtain a high-quality connection due to the fact that the current is turned off until the welding pressure is relieved, resulting in cracking of the tungsten contacts, because the metals being joined have different thermal and physical properties.
Цель изобретени - повышение качества сварного соединени .The purpose of the invention is to improve the quality of the welded joint.
Это достигаетс тем, что усилие сжати снимают одновременно с выключением сварочного тока.This is achieved by the fact that the compression force is removed simultaneously with the switching off of the welding current.
Процесс контактной точечной сварки осуществл ют на м гких режимах сварки и усилие сжати электродов снимают одновременно с выключением сварочного импульса.The resistance spot welding process is carried out under soft welding conditions and the compression force of the electrodes is removed simultaneously with the welding pulse off.
На контактной машине МТПК 25-1 сварена парти образцов, представл ющих собой соединени вольфрамовых контактов толщиной 1 мм с пластиной пз углеродистой стали толщиной 0,5 мм, прочностные испытани которых показывают 150-170 кг на срез, чтс соответствует требовани м те.хнических уело ВИЙ на изготовление р да деталей автотрак торной промышленности.On the MTPK 25-1 contact machine, a batch of specimens is welded, which are joints of tungsten contacts 1 mm thick with a plate pz of carbon steel 0.5 mm thick, the strength tests of which show 150-170 kg per cut, which corresponds to the requirements of mechanical VIY for the manufacture of a number of parts for the automotive industry.
