Abstract

Sposób wytwarzania napoin zwłaszcza na odlewach z żeliwa szarego z grafitem płatkowym lub kulkowym lub wermikularnym, w którym stosuje się napawanie plazmowe albo metodą MIG/MAG polega na tym, że na odlew nakłada się cyklicznie odcinki napoiny. Nakładanie napoiny prowadzi się na zimnym odlewie, a kolejny odcinek napoiny nakłada się tak, aby nachodził na wcześniej położony odcinek napoiny. Długość odcinka napoiny jest równa szerokości napoiny, Po wykonaniu napoiny odlew umieszcza się w piecu i wytrzymuje się go w nim w czasie co najmniej 2 godzin. Sposób, będący przedmiotem wynalazku, pozwala na wytwarzanie napoin skoncentrowanym strumieniem ciepła na zimno na żeliwnych odlewach armatury. W wyniku jego zastosowania uzyskuje się brak pęknięć materiału odlewu armatury i napoiny wytworzonej metodą napawania plazmowego albo metodą MIG/MAG.The method of producing surfacing welds, especially on gray iron castings with flake or ball or vermicular graphite, in which plasma surfacing or by MIG / MAG method is applied, consists of cyclical weld sections. The surfacing weld is applied on a cold casting, and the next surfacing stretch is applied so that it overlaps with the previously laid surfacing stretch. The length of the surfacing section is equal to the width of the surfacing layer. After making the surfacing casting is placed in the furnace and withstands it for at least 2 hours. The method, which is the subject of the invention, allows the production of surfacing welds with a concentrated stream of cold heat on cast iron fittings. As a result of its application, there are no cracks in the cast material of the fittings and surfacing welds produced by plasma welding or MIG / MAG.
