Abstract
A method for friction stir welding using liquid cooling. The method includes the steps of moving a pin tool across a welding location, spraying a cooling liquid in a localized manner from a cooling ring moving with the pin tool onto a trailing region and onto lateral regions of the welding location adjacent to the pin tool, and blowing cooling gas from a gas jet moving with the pin tool from a front of the pin tool against the pin tool and against the cooling liquid emerging from the cooling ring. In addition, a friction stir welding and cooling device includes a pin tool configured to move across a welding location and a cooling ring at least partially encircling the pin tool. The cooling ring is configured to move simultaneously with the pin tool across the welding location and includes a plurality of nozzles configured to spray a cooling liquid. The nozzles are arranged such that the cooling liquid emerging from the nozzles is localized at a trailing region and at lateral regions of the welding location adjacent the pin tool.
