The paper presents the characteristics of innovative technology of micro-jet cooling in MIG welding (according to PN-EN ISO 4063:2009). Presented results received at different jet hole geometry and various coolant pressure. This technology allows get, with appropriately selected parameters of cooling increased ferrite AF content in weld metal, up to 14% for standard MIG technology. This structure proves toughness, especially at temperature -40 degree Celsjus.

W pracy scharakteryzowano innowacyjną technologię chłodzenia mikrojetowego podczas spawania metoda MIG (zgodnie z norma PN-EN ISO 4063:2009). Przedstawiono wyniki badań uzyskanych przy różnych ustawieniach geometrycznych otworów chłodzących oraz różnym ciśnieniu medium chłodzącego. Zastosowanie tej technologii pozwala uzyskać, przy odpowiednio dobranych parametrach chłodzenia większą zawartość ferrytu AF w stopiwie, do 14% w odniesieniu do standardowej technologii MIG. Ma to wpływ na udarność, szczególnie przy temperaturze -40 stopni Celsjusza.
