Jednym z parametrów punktowego zgrzewania tarciowego z mieszaniem z zamknięciem krateru RFSSW jest zagłębienie tulei narzędzia w łączone komponenty. Wartość zagłębienia zależy m.in. od grubości łączonych blach i tolerancji z jaką wykonano blachy oraz od pozostałych parametrów procesu RFSSW. Celem pracy było określenie wpływu zagłębienia narzędzia na jakość punktowych złączy RFSSW. Przedmiotem badań były złącza wykonane z blach ze stopu aluminium 2024-T3 o grubości 1,0 mm i stopu aluminium D16UTW o grubości 0,6 mm. Zgrzewanie następowało od strony blachy wykonanej ze stopu aluminium 2024-T3. Testowano trzy poziomy zagłębienia tulei, bez zmiany pozostałych parametrów zgrzewania. Zagłębienia wynosiły 1,10 mm, 1,15 mm i 1,20 mm. Dla każdego wariantu wykonano 10 zgrzein RFSSW. Osiem z nich służyło ocenie nośności złączy z uwzględnieniem analizy odkształceń zredukowanych, jedna z nich ocenie makrostrukturalnej, a jedna ocenie wizualnej.

One of the parameters of Refill Friction Stir Spot Welding is a tool sleeve depth in the joined components. The value of the depth depends on inter alia joined sheets thicknesses, a tolerance with which the sheets were made and the other parameters of the RFSSW process. The aim of the work was to determine the impact of tool depth on the quality of the RFSSW joints. Joints made of an aluminum alloy 2024-T3 sheet having a thickness of 1.0 mm and an aluminum alloy D16UTW sheet having a thickness of 0.6 mm were analysed. The welding was performed on the side of the sheet made of aluminum alloy 2024-T3. Three tool depths without changing the other welding parameters were tested. The tool depths were following: 1.10 mm, 1.15 mm and 1.20 mm. For each variant 10 RFSSW welds were made. Eight of them were served to assess the load bearing capacity of the joints with consideration plastic strain analysis, one of them were for macrostructural assessment, and one of them were for a visual assessment.
