Joining phenomena of stainless steel/aluminium alloy joint welded by Thermal Compensation resistance spot welding
International Journal of Materials & Product Technology, 2014Co-Authors: Hua Yu, Keke ZhangAbstract:Aluminium alloy and austenitic stainless steel were welded using a Thermal Compensation resistance spot welding technology. The interface region was observed using electron microscopy, and the temperature distribution on the welding zone was investigated as well. The results reveal that higher heat can be obtained in Thermal Compensation resistance spot welding in comparison with conventional one, and that the morphology and thickness of the reaction layer vary with the position at the welding interface.

Properties of Light Metal Joint Welded by Thermal Compensation Resistance Spot Welding
Advanced Materials Research, 2011Co-Authors: Yi Min Tu, Hua Yu, Keke ZhangAbstract:A new technique of Thermal Compensation resistance spot welding was used to weld light metal such as aluminum alloy sheet and magnesium alloy. The effects of welding parameters on the tensile shear strength of joint and nugget diameter were investigated. The tensile shear load and nugget of the joint increased with the increasing of welding time, whereas that of the joint decreased with the increasing of electrode force. The joint with the maximum tensile shear load of approximately 5 kN was obtained at the condition of 12 kA and 11 kA welding current for aluminum alloy and magnesium alloy, respectively. The results reveal that the Thermal Compensation resistance spot welding is a feasible method to weld aluminum alloy and magnesium alloy..

IECON - Sensorless Position Estimation with Thermal Compensation for Compact Dual Solenoid Actuator
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018Co-Authors: Sakahisa Nagai, Atsuo KawamuraAbstract:This study aims to realize a tactile display which can represent 2D haptic information on the display surface. The display consists of many compact actuation systems whose position and force can be controlled. In our previous works, sensorless motion control for a compact solenoid actuator has been proposed to realize the compact actuation system. Additionally, we have proposed sensorless control method for a dual solenoid actuator (DSA) to improve the control performance. However, the proposed DSA system has a few problems such as large body, large mover mass, and large friction force. In order to solve these problems, this paper proposes a new compact dual solenoid actuator (CDSA). The proposed actuator has less number of coil turns, therefore much current is required to generate large magnetic force. On the other hand, the large current generates large Thermal energy which causes change of the inductance characteristics of the dual coils. The sensorless position estimation is conducted using the relation between the mover position and the inductance. Therefore, Thermal Compensation method for the new CDSA is also proposed in this paper. Experiments were conducted to validate the proposal. As a result, the sensorless position estimation with less than 60μm estimation error was achieved.
