EN

Laser is widely applied in micro welding. Apart from that method, welding with micro-jet cooling could be treated as another important method for thin structure welding. Until that moment micro-jet technology is not very popular. An article presents actual information about innovate welding technology with micro-jet cooling in comparison with standard laser welding. There were given information about influence of both micro welding method on metallographic structure of thin steel welds. Amount of AF was tested in two cases.

Laser jest szeroko stosowany w mikro-spawaniu. Oprócz tej metody, spawanie z chłodzeniem mikrojetowym powinno być traktowane jako ważna metoda spawania cienkościennych konstrukcji. W artykule przedstawiono innowacyjną technologię spawania z chłodzeniem mikrojetowym w porównaniu do spawania laserowego. Uzyskano informacje o wpływie obu metod na strukturę metalograficzną stalowych cienkościennych konstrukcji. Zawartość ferrytu AF była porównana w obu przypadkach.
