TL;DR: In this paper, the authors applied FSpW to join the 6061-T4 aluminum alloy sheet with 2mm thickness and found that the tensile/shear strength reached the maximum of 7117.0 and 4555.4 N at the welding condition of the rotational speed of 1500rpm and duration time of 4 s.

06 Jul 2001TL;DR: In this paper, the authors used welding data in an energy balance model in integral form to estimate the mean weld temperature and to predict process conditions such as occurrence of splash, and weld diameter.
Abstract: Methods and apparatus are provided for monitoring resistance spot welding process conditions in real time by using welding data in an energy balance model in integral form to estimate the mean weld temperature and to predict process conditions such as occurrence of splash, and weld diameter. Using predicted welding process conditions, welding parameters are modified in real time to prevent splash and produce sound welds.

TL;DR: In this article, the failure of friction stir spot welds in aluminum 6061-T6 lap-shear specimens is investigated based on experimental observations, where the failure is initiated near the possible original notch tip in the stir zone (SZ) and the failure propagates along the circumference of the nugget to final fracture.
