Effect of surface condition on resistance spot welding of advanced high strength steel
(University of Waterloo, 2019-09-25)Advanced high strength automotive sheet steel (AHSS) is used in body-in-white design to reduce vehicle weight while maintaining high crashworthiness. Surface coatings applied to AHSS to protect it from oxidation and ... -
Investigation of Liquid Metal Embrittlement in Advanced High Strength Steels
(University of Waterloo, 2020-04-17)Third-generation advanced high strength steels (AHSS) are typically given a zinc coating that provides excellent resistance to corrosion. During the resistance spot welding (RSW) process, the melted zinc coating enables ... -
Liquid Metal Embrittlement in Resistance Spot Welding: The Thermomechanical Origin and Embrittler Transport Mechanism
(University of Waterloo, 2021-08-05)To increase fuel economy, demand for lighter vehicles by way of thinner parts has risen in recent years. As parts become thinner the vehicle safety cannot be comprised, leading to the development of advanced high strength ... -
Microstructural Development and Weldability Optimization in the Resistance Spot Welding of Quenched and Partitioned Steels
(University of Waterloo, 2021-04-16)Advanced high-strength steels (AHSS) have been widely used in the automotive industry to meet the demand for reduced fuel consumption and environmental emissions. Quenching and Partitioning (Q&P) is a heat-treatment method ... -
A Statistical Approach to Quantifying Impact of Multiple Pulse Resistance Spot Welding Schedules on Liquid Metal Embrittlement Cracking
(University of Waterloo, 2019-04-26)Advanced high strength steels (AHSS) are advantageous for automotive applications due to their excellent strength and ductility. However, when coated with zinc for corrosion protection, these steels are susceptible to ...
