Mechanical characteristics of laser braze-welded aluminium–copper connections

Abstract: The mechanical characteristics of dissimilar Al–Cu connections, joined by a novel, robust laser braze-welding process are reported. A fiber laser is used in combination with a 2D galvoscanner to provide spatial power modulation by superposed circular beam oscillation. With the help of statistical experimental design, a broad range of processing parameters has been investigated in order to understand their effects on the joint characteristics. A maximum shear strength of 121 MPa has been detected within the scope of the experiments.

Electrical performance of laser braze-welded aluminum–copper interconnects

TL;DR: In this article, a laser beam braze-welding technology for dissimilar aluminum-copper interconnects for Li-ion battery assembly was investigated and it was proved that highest shear strength and lowest contact resistance can be achieved within the same parameter set.

Position Identification in Force-Guided Robotic Peg-in-Hole Assembly Tasks

TL;DR: In this article, an EM-GMM-based Contact State (CS) model was used to detect the phase of the peg-on-hole phase in force-guided robotic peg-in-hole assembly.
Journal ArticleDOI

Contact-State Monitoring of Force-Guided Robotic Assembly Tasks Using Expectation Maximization-based Gaussian Mixtures Models

TL;DR: The proposed EM-GMM would accommodate the signals nonstationary behavior and the EM algorithm would guarantee the estimation of the optimal parameters set of the GMM for each signal, and hence the modeling accuracy would be significantly enhanced.
