Basic weld design in mechanical engineering is a fairly mature practice today and teaching this to students in the typical undergraduate program is straight forward for the most part. However, one concept that is slightly confusing to students is the design of fillet welds in the transverse and parallel orientations. The non-ideal nature of fillet weld profiles (e.g., irregular and bumpy surfaces) has led to an empirical-based design approach with simplifying and conservative assumptions. At the end, students do learn the process steps and are able to design welds as expected, but a more thorough understanding of the fundamentals of these weld types would be beneficial. To aid teaching and learning of fillet weld design, a small student-led project was conducted that included a comparison of results from theoretical, numerical, and experimental studies of parallel and transverse fillet welds. It’s thought that the three-pronged study will facilitate learning, as would be expected with any hands-on approach. The main study goal is to investigate the differences in strength in these two fillet weld orientations and compare the corresponding results to theoretical design approaches presented in codes and textbooks. For this study, three transverse fillet weld and three parallel fillet weld coupons were fabricated and then tested until fracture with a tensile test machine. The stresses found at failure were then compared to corresponding results from theoretical calculations and finite element analysis studies. Three students from a mechanical engineering program led the project, all of whom were enrolled in the senior-level Machine Design course at the time – the typical course where weld design is taught. This project is a work-in-progress, with completion expected in February 2023. Results will include all numerical data and comparisons from all three studies, as well as qualitative feedback from the three students and two participating engineering faculty on the value of the project to conceptual understanding of the topic.
