Description
Przedmiotem wynalazku jest sposób spawania elektrycznego z podgrzewaniem elektrody oraz glowica spawalnicza.The subject of the invention is a method of electric welding with electrode heating and the head welding.
Znany jest sposób spawania automatycznego lub pólautomatycznego, w którym prad doprowadzony jest do elektrody jednym zaciskiem pradu spawania. Ze wzgledu na konstrukcje znanych urzadzen spawalniczych i zaleznosc swobodnego wylotu elektrody od zacisku nie mozna zwiekszyc wspólczynnika stapiania elektrody.There is known a method of automatic or semi-automatic welding in which the current is applied to the electrode with one welding current clamp. Due to the design of well-known welding devices and the dependence of the free outlet of the electrode on the clamp cannot increase the melting factor of the electrode.
Zmienna dlugosc swobodnego wylotu elektrody umozliwia niewielkie zwiekszenie szybkosci stapiania tylko dla stosunkowo malych srednic elektrod.The variable length of the free electrode outlet allows a slight increase in the fusion rate only for relatively small diameter of the electrodes.
Sposób spawania elektrycznego wedlug wynalazku polega na wstepnym podgrzewaniu elektrody z dodatkowego zródla pradu o wartosciach 40-900 A, w zaleznosci od ustalonej technologii dla danej metody spawania.The method of electric welding according to the invention consists in preheating the electrode from an additional source of current with a value of 40-900 A, depending on the technology established for a given method welding.
Glowica do spawania elektrycznego, zawierajaca zacisk pradu spawania oraz urzadzenie napedowe elektrody, wyposazona zostala w dodatkowy zacisk pradu podgrzewania, usytuowany miedzy rolkami napedowymi elektrody i zaciskiem pradu spawania, przy czym zródlo pradu podgrzewania polaczone z zaciskiem pradu spawania oraz dodatkowym zaciskiem pradu podgrzewania.Electric welding head, including a welding current clamp and a driving device electrodes, is equipped with an additional heating current clamp, located between the rollers electrode drive and welding current clamp, the source of the heating current connected with a welding current clamp and an additional heating current clamp.
Zastosowanie sposobu i glowicy wedlug wynalazku zwiekszy wspólczynnik stapiania elektrody w grani¬ cach 30—70% w zaleznosci od przyjetej technologii spawania. Rozwiazanie moze byc stosowane zarówno do glowic automatów jak i uchwytów spawalniczych, przy czym moze byc zastosowane do spawania i napawania lukiem krytym w metodzie elektro-zuzlowej oraz w oslonie C03.The use of the method and the head according to the invention will increase the root fusion factor of the electrode 30-70%, depending on the welding technology adopted. The solution can be used for both heads of automatic machines and welding torches, and can be used for welding and surfacing a hidden hatch in the electroslag method and in the C03 sheath.
Przedmiot wynalazku jest przedstawiony na rysunku schematycznym. Glowica do spawania zawiera zacisk 1 pradu spawania oraz urzadzenie napedowe w postaci rolek 2 do przesuwania elektrody 3 w kierunku materialu 4 spawanego. Pomiedzy rolkami 2 i zaciskiem 1 pradu spawania umieszczony jest dodatkowy zacisk 5 pradu podgrzewania. Zródlo pradu podgrzewania polaczone jest z zaciskiem 1 pradu spawania oraz dodatkowym zaciskiem 5 pradu podgrzewania. Przyklad spawania automatycznego lukiem krytym:2 101 637 prad spawania napiecie luku predkosc spawania srednica elektrody Is = 575 A U=40V s = 25 m/h ip = 4 mm Bez dodatkowego podgrzewania elektrody wspólczynnik stapiania wynosi: 14 G/Ah.The subject of the invention is shown in the schematic drawing. The welding head includes a clamp 1 of the welding current and a drive device in the form of rollers 2 for moving the electrode 3 towards the material 4 welded. An additional current clamp 5 is located between the rollers 2 and the welding current clamp 1 heating. The source of heating current is connected to the welding current terminal 1 and the additional one terminal 5 for heating current. Example of automatic arc welding: 2 101 637 welding current hatch tightness welding speed electrode diameter Is = 575 A. U = 40V s = 25 m / h ip = 4 mm Without additional heating of the electrode, the deposition factor is: 14 G / Ah.
Z podgrzewaniem dodatkowym elektrody pradem o wartosci lp = 400 A wspólczynnik stapiania elektrody wynosi 23 G/Ah, co daje wzrost tego wspólczynnika o 64%.With additional heating of the electrode with a current of lp = 400 A, the melting factor of the electrode equals 23 G / Ah, which increases this ratio by 64%.
Spawanie przebiega tak samo jak w znanych sposobach, to jest przez zapewnienie styku elektrody z materialem spawanym, otwarciem zsypu topnika i wlaczeniem pradu spawania. Po wyregulowaniu podanych w instrukcji parametrów spawania, wlacza sie przesuw jazdy wózka z równoczesnym wlaczeniem dodatkowego pradu podgrzewania elektrody 3.Welding is carried out in the same way as in the known methods, i.e. by bringing the electrode into contact with the workpiece, opening the flux chute and switching on the welding current. After adjusting the given in the welding parameters manual, the trolley travel is included with the simultaneous activation of the additional one electrode heating current 3.
Czas ustalenia sie procesu spawania ze stala temperatura konca swobodnego wylotu elektrody 3, w zaleznosci od wartosci prdu podgrzewania waha sie w granicach 5—10 sek. Po tym czasie przeprowadza sie korekte napiecia i natezenia pradu spawania.Time to establish the welding process with the constant temperature of the end of the free electrode outlet 3, depending on the value of the heating current, it ranges from 5 to 10 sec. After that time he moves out correction of voltage and welding current intensity.
Przy tej samej konstrukcji glowice automatów i uchwytów spawalniczych mozna spawac w oslonie C02 przy prawie identycznych czynnosciach procesu spawania.With the same design, the heads of automatic and welding torches can be welded in a C02 shield with almost identical steps in the welding process.
