Resistance Spot Welding and Multi-Material Automotive Design

The live presentation of this event has already taken place.

This webinar describes the resistance spot welding (RSW) process that is primarily used in the joining of the automotive Body in White (BiW). Automotive BiW has on average about 2000 to 5000 spot welds, used to join different parts of the BiW made from different materials or thicknesses. The process has different parameters such as welding current, weld time, weld force, and electrode diameter that individually and in combination affect the spot weld quality and mechanical strength. The strength of the individual spot weld plays a role in ensuring that it can sustain the impact load without failing and maintaining the structural stiffness and noise, vibration, and harshness (NVH) performance of the BIW while providing safety for passengers.

In recent years, automotive structure design has moved towards multi-materials design (MMD) in creating lightweight structures, improved crashworthiness, and reduced CO2 emission. Materials such as aluminum alloys, magnesium, and polymer composites are being introduced as part of the MMD strategy to replace the traditionally used steels. This webinar will provide an overview of the challenges faced in using RSW in joining materials other than steel. The webinar will also explain process changes in RSW to weld composite joints and alternative welding methods that are currently being used to replace RSW.

Presenter: Dr. Aravinthan Arumugam, EIT Lecturer and Unit Coordinator

Aravinthan Arumugam has 20 years of experience spread between industrial practice, engineering consultancy, research and development, and academia. He obtained his BEng (Hons) in Mechanical Engineering (1st Class Honours) and PhD in Engineering from Nottingham Trent University, United Kingdom.

Aravinthan has been an academic in different institutions of higher education in Malaysia and Perth, Australia. He is currently a Unit Coordinator and Lecturer at EIT and teaches units within the Department of Mechanical Engineering. He is also the Program Leader for EIT’s Advance Diploma in Mechanical Engineering.

Aravinthan’s research expertise and interest are in welding technologies and is currently involved in research related to spot welding and friction spot welding. Aravinthan is also a Chartered Engineer (CEng) with the Institution of Mechanical Engineers IMechE (UK) and a Chartered Professional Engineer (CPEng) with Engineers Australia.
