摘要

本文采用响应面法（RSM）和灰色关系分析法（GRA）对铝铜脉冲激光焊接的工艺参数进行了研究，以提出接头搭接剪切强度的最佳方向。通过单因素实验找到了合适的工艺参数窗口。以激光功率、焊接速度、脉冲宽度和频率为输入，以接头搭接剪切力、界面焊接宽度和焊接渗透深度为输出，建立并分析了 RSM 模型。利用界面焊缝宽度和焊缝熔透深度与接头搭接剪切力的 GRA，提出了接头搭接剪切力的改进方向。

Optimization and GRA prediction of Al–Cu pulsed laser welding process based on RSM

In this paper, the process parameters of pulsed laser welding of Al–Cu are studied using response surface methodology (RSM) and grey relation analysis (GRA) to propose optimal directions for lap-shear strength of the joints. A single-factor experiment was conducted to find the suitable process parameter windows. The RSM models were established and analyzed with laser power, welding speed, pulse width, and frequency as inputs and joint lap shear, interfacial weld width, and weld-penetration-depth as outputs. With the use of GRA of interfacial weld width and weld penetration depth with the lap-shear force of joints, the improved direction for the lap-shear force of joints can be proposed.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
