Description
Przedmiotem wynalazku jest sposób spawania metali, zwlaszcza o duzym powinowactwie do tlenu bez dodatku spoiwa, który jest szczególnie przydatny w przypadku wykonywania spoin krawedziowych w zlaczach brzegowych.Stan techniki. Znany sposób spawania metali bez dodatku spoiwa polega na stapianiu uprzednio przygotowanych powierzchni w temperaturze wytworzonej w luku elektrycznym pomiedzy elektroda wolframowa a materialem spawanym. Otrzymywane zlacza brzegowe maja szereg wad, z których podstawowa jest wystepowanie nieciaglosci metalurgicznej na przedluzeniu szczeliny pomiedzy laczonymi elementami siegajacej do okolo 50% wtopienia. W dostepnych publikacjach fachowej literatury krajowej i zagranicznej opisywana jest wyzej wspomniana nieciaglosc jako wada powaznie obnizajaca jakosc i zlacza brzegowego, wystepujaca nagminnie przy spawaniu metali niezelaznych oraz metali o duzym powinowactwie do tlenu.Istota wynalazku. Sposób wedlug wynalazku spawania metali, zwlaszcza o duzym powinowactwie do tlenu polega na tym, ze w trakcie spawania laczonych elementów wprowadza sie w obszar stopionego metalu precik wykonany z materialu o temperaturze topnienia wyzszej od temperatur topnienia spawanych metali. Precikiem wykonuje sie ruch drgajacy i przesuwa sie go jednoczesnie z ruchem palnika wzdluz linii*spawania.Korzystne skutki techniczne wynalazku. Zastosowanie sposobu wedlug wynalazku eliminuje calkowicie nieciaglosc metalurgiczna spoiny, a tym samym likwiduje wystepowanie bardzo niekorzystnego karbu strukturalnego oraz znaczne zwiekszenie glebokosci wtopienia w porównaniu ze spoinami uzyskiwanymi dotychczas stosowanymi sposobami.Przyklad wykonania sposobu wedlug wynalazku. Sposób wedlug wynalazku zostanie blizej wyjasniony na przykladzie spawania elementów wykonanych z aluminium. Po wstepnej obróbce powierzchni elementów wykonanych z aluminium przeznaczonych do spawania polegajacej na odtluszczeniu i wytrawieniu zamocowuje sie je w specjalnie uchwycie mocujacym. Powierzchnie przeznaczone do spawania sklada sie w ten sposób aby uzyskac zlacze brzegowe. Po przekroczeniu temperatury topnienia metalu za pomoca luku elektrycznego. Do2 97 496 obszaru stopionego metalu wprowadza sie precik wolframowy, który prowadzi sie wzdluz linii spawania wraz z palnikiem i jednoczesnie wykonuje sie nim ruch drgajacy. PLThe subject of the invention is a method of welding metals, especially with a high affinity for oxygen, without the addition of a binder, which is particularly useful in the case of making edge welds in edge joints. State of the art. The known method of welding metals without the addition of a binder consists in fusing previously prepared surfaces at the temperature generated in the electric arc between the tungsten electrode and the welded material. The obtained edge joints have a number of drawbacks, the main of which is the occurrence of metallurgical discontinuity in the extension of the gap between the joined elements, reaching up to about 50% of fusion. In the available publications of the professional domestic and foreign literature, the above-mentioned discontinuity is described as a defect that seriously reduces the quality of the edge joint, common in welding non-ferrous metals and metals with high affinity for oxygen. The method according to the invention of welding metals, especially those with high affinity for oxygen, consists in the fact that during welding of the joined elements, a stain made of a material with a melting point higher than the melting point of the welded metals is introduced into the area of the molten metal. The precik makes a vibrating motion and moves it simultaneously with the movement of the torch along the welding line. Advantageous technical effects of the invention. The use of the method according to the invention completely eliminates the metallurgical discontinuity of the weld, and thus eliminates the occurrence of a very unfavorable structural notch and a significant increase in the depth of penetration compared to the welds obtained with the methods used hitherto. An embodiment of the method according to the invention. The method according to the invention will be explained in more detail on the example of welding of elements made of aluminum. After the surface of the aluminum elements to be welded is pre-treated by degreasing and etching, they are fixed in a special mounting holder. The surfaces to be welded are folded in such a way as to obtain an edge joint. After exceeding the melting point of the metal with the help of an electric arc. A tungsten stalk is introduced into the area of molten metal, which is guided along the welding line with the torch and simultaneously vibrates. PL
