摘要

铝合金AA6061和低碳钢Q235采用铝铆钉作为元件，采用电阻元件焊接而成。对接头的组织和性能进行了表征。利用ABAQUS数值模拟软件计算了接头截面上的温度分布。接头截面上的观察结果表明，在铆钉头与底板钢的交界面处形成了一个核块。焊接电流为26 kA时，接头的最大拉伸剪切载荷为5.82 kN。研究表明，铝合金与低碳钢电阻元件焊接接头的承载界面为铝合金的同类界面，对接头起到强化作用。

Resistance element welding of aluminium alloy and steel using an element of aluminium

Aluminium alloy AA6061 and mild steel Q235 were welded by resistance element using an aluminium rivet as the element. The microstructure and properties of the joints were characterised. The temperature distribution on the cross-section of the joints was calculated by using ABAQUS numerical simulation software. The observation results on the cross-section of the joints show a nugget formed at the interface between the rivet tip and steel of lower plate. The maximum tensile shear load of the joints reached 5.82 kN at the welding current of 26 kA. This study reveals that the bearing interface of the resistance element welded joint between aluminium alloy and mild steel is like-to-like interface of aluminium alloy which strengthens the joint.

期刊介绍： Science and Technology of Welding and Joining is an international peer-reviewed journal covering both the basic science and applied technology of welding and joining. Its comprehensive scope encompasses all welding and joining techniques (brazing, soldering, mechanical joining, etc.) and aspects such as characterisation of heat sources, mathematical modelling of transport phenomena, weld pool solidification, phase transformations in weldments, microstructure-property relationships, welding processes, weld sensing, control and automation, neural network applications, and joining of advanced materials, including plastics and composites.
