Weld strength in inertia welding experiment
Use the diagram on this page to emphasise the difference between a confidence interval for the mean response and a prediction interval for a new response value.
Use the slider to display both intervals at different x-values. (The coloured bands summarise.)
Manufacturers use inertia welding to join different metals that cannot easily be joined by other means (e.g. aluminium to steel). One part of a workpiece is attached to a flywheel that is rotated at speed and forced into contact with another piece that is restrained from rotating. The heat generated by friction at the interface produces a hot-pressure weld.
The data contain results from an inertia welding experiment. The two variables in the experiment were the velocity (ft per minute) of the rotating workpiece and the breaking strength of the weld.
