Characterization of Material Properties of 2xxx Series Al-Alloys by Non Destructive Testing Techniques
TL;DR: In this paper, material properties of 2xxx series Al-alloys were characterized by eddy current and ultrasonic NDE techniques so that the inspection can be carried out effectively in the shortest possible time.
Journal ArticleDOI
Ultrasonic nondestructive evaluation of spot welds for zinc-coated high strength steel sheet based on wavelet packet analysis
TL;DR: In this paper, a wavelet packet transform (WPT) processing is adopted to analyze the ultrasonic signals acquired by the pulse echo from spot welds for nondestructive evaluation to the spot weld.
Journal ArticleDOI
Tests of thin-walled beams joined by spot welding
TL;DR: In this paper, the axial compression tests of thin-walled beams joined by spot welding were performed and the effect of the size of the weld's diameter and the pitch of the welding on the amount of absorbed energy was studied.
Journal ArticleDOI
Ultrasonic evaluation of friction stud welded AA 6063/AISI 1030 steel joints
TL;DR: In this article, the tensile strength of AA 6063/AISI 1030 joint was found to be 36.64% and 78.15% lower than that of AA6063 and AISI1030 respectively.
Journal ArticleDOI
Ultrasonic test of resistance spot welds based on wavelet package analysis.
TL;DR: It is indicated that traditional ultrasonic signal analysis in either time domain or frequency domain remains inadequate to evaluate the nugget diameter of spot welds, but the method based on wavelet package analysis in time-frequency domain can easily distinguish the nuggets from the corona bond by extracting high-frequency signals.
