Изобретение относитс к способу эпектродуговой сварки и наплавки в среде защитных газов и может быть использовано при наплавке электрических контактов.The invention relates to a method of arc welding and surfacing in a protective gas environment and can be used in surfacing electrical contacts.
Известен способ электродуговой сварки в среде защитных газов, по которому управление переносом электродного металла осуществл ют импульсами направленного потока защитного газа.The known method of electric arc welding in shielding gases, by which the transfer of the electrode metal is controlled by pulses of a directional flow of shielding gas.
При таком способе усложнена пускорегулирующа и газоподающа аппаратура и велик расход защитного газа.With this method, the start-up and gas-supply equipment is complicated and the protective gas consumption is high.
Предлагаемый способ отличаетс от известного тем, что сброс капель осуществл етс ударом по ним токоподвод щего Л1унд щтука, совершающего вертикальное возвратно-поступательное движeiiиe с регулируемой частотой и скоростью перемещени , что снижает расход защитно го газа, позвол ет получить капли электродного металла заданкогс веса и обеспечивает регулирование частоты и скорости перемещени капель к изделию.The proposed method differs from the well-known fact that droplets are dropped by striking a current-carrying L1und brush on them, performing a vertical reciprocating movement with an adjustable frequency and speed of movement, which reduces the flow of protective gas, produces electrode drops of a given weight and provides control of the frequency and speed of movement of the droplets to the product.
Способ по сн етс чертежом.The method is explained in the drawing.
После возбуждени дуги и подачи электрода на его торце в непосредственной бпизости от мундштука 1 формируетс капл 2 расплавленного металла. При достижении ЗсЬданных размеров капли токоподвод ший мундштук перемещают вниз. Он наносит удар по капле и отдел ет ее от электрода. Зате.; мундштук возвращаетс в исходное положение , и цикл повтор етс .After initiating the arc and supplying the electrode, a drop of molten metal is formed at its end in the immediate vicinity of the mouthpiece 1. When the drop size is reached, the current lead mouthpiece is moved down. It strikes a drop and separates it from the electrode. Then .; the mouthpiece returns to its original position and the cycle repeats.
Измен скорость перемещени мундштука , получают различные скорости движехш капель к изделию, а регулиру скорость подачи электрода и задава частоту ударов мундштука, .вес капель регулируют в широком интервале.By changing the speed of movement of the mouthpiece, different speeds of movement of the drops to the product are obtained, and by adjusting the feed rate of the electrode and setting the frequency of blows of the mouthpiece, the weight of the drops is adjusted over a wide range.
Способ может быть использован при наплавке электрических контактов из золота, серебра и их сплавов, при этом процесс ocjществл етс на малых токах пор дка 5-10 а с применением электродной проволоки диаметром 0,6-1,2 мм.The method can be used for surfacing electrical contacts made of gold, silver and their alloys, while the process takes place at low currents of the order of 5-10 a using electrode wire with a diameter of 0.6-1.2 mm.
