Abstract

Recently, the usage of laser transmission welding (LTW) technology in the automotive industry has been rising for joining thermoplastic parts regarding its superior properties in comparison to other welding technologies. However, specifying the process parameters is a crucial step to obtain satisfactory welding quality for the vehicle parts. In this context, this paper addresses the LTW process of Polimetil metakrilat (PMMA) to Akrilonitril bütadien stiren (ABS) materials for the production of taillights in an automotive company and proposes a new multi-response Taguchi-Based TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method to optimize machining parameters in the laser welding process. In the proposed solution methodology, the main effects of the parameters on different outputs are identified by using the L 16 orthogonal array of the Taguchi method. Regarding the best parameter set for each output, the best parameter set for multi-response is identified by using the TOPSIS method, in which alternatives are evaluated through the interrelated quality measures. To optimize welding process in taillight production, PMMA and ABS samples with the dimensions of 40 mm in width, 85 mm in length, and 2 . 7 mm in thickness are used in the experiments. The samples are welded by using LPKF Twinweld 3D 6000® laser welding machine. For the welding process, laser power, welding speed, and pressure force are taken into account as the input parameters to optimize three responses: weld strength, breaking strain, and weld width. To identify the best process parameter values, the Taguchi Method is initially employed to calculate the main effects of LTW parameters for each output. Then, the TOPSIS method is carried out to evaluate a number of alternative parameter sets generated through the Taguchi results. As a consequence of the TOPSIS ranking scores, the best parameter set that jointly optimizes three outputs of the LTW process is identified for the taillight production as 60 W power, 100 mm / s speed, and 150 N pressure force. Based on the conducted experiments, this parameter setting achieves the highest weld strength, breaking strain level, and above-average weld width. The results of the experiments show that the proposed methodology is capable of optimizing LTW parameters for a multi-response with fewer experiments in the joining of plastic vehicle parts.

基于Taguchi-based TOPSIS方法的PMMA - ABS激光传输焊接多响应优化

近年来，激光传输焊接(LTW)技术在汽车工业中的应用越来越多，因为它与其他焊接技术相比具有优越的性能。而工艺参数的确定是保证汽车零部件焊接质量的关键环节。针对某汽车公司尾灯用聚甲基丙烯酸甲酯(PMMA)与丙烯酸甲酯(ABS)材料的LTW工艺，提出了一种基于田口多响应的TOPSIS (technical for Order of Preference by Similarity to Ideal Solution)方法，对激光焊接工艺中的加工参数进行优化。在提出的求解方法中，利用田口法的l16正交阵列确定了参数对不同输出的主要影响。对于每个输出的最佳参数集，使用TOPSIS方法确定多响应的最佳参数集，其中通过相互关联的质量度量来评估备选方案。为了优化尾灯生产中的焊接工艺，采用PMMA和ABS样品，尺寸分别为宽40mm，长85mm，宽40mm。实验中使用的厚度为7mm。样品采用LPKF Twinweld 3D 6000®激光焊接机焊接。在焊接过程中，考虑激光功率、焊接速度和压力作为输入参数，优化焊缝强度、断裂应变和焊缝宽度三个响应。为了确定最佳工艺参数值，首先采用田口法计算LTW参数对每个输出的主要影响。然后，采用TOPSIS方法对由田口结果生成的多个备选参数集进行评估。根据TOPSIS排名得分，对于尾灯生产，LTW工艺的三个输出的最佳参数集被确定为60 W功率、100 mm / s速度和150 N压力。根据所进行的实验，该参数设置获得了最高的焊缝强度、断裂应变水平和高于平均水平的焊缝宽度。实验结果表明，所提出的方法能够以较少的实验次数优化汽车塑料零件连接的多响应LTW参数。

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.
