Which welding process is most sustainable for EV battery enclosures? Our life cycle assessment compares emissions, energy use, and materials across four joining methods.Compare welding methods for EV battery enclosures using LCA to determine environmental impacts and improve sustainable automotive manufacturing.| AHSS Guidelines
Tensile testing is one of the most basic formability characterization methods available. Results from tensile testing are a key input into metal forming simulations.| AHSS Guidelines
Automakers face conflicting constraints when designing new body structures: With escalating concerns about human-induced green-house gases, global legislators have passed increasingly stringent vehicle emissions regulations, with even more aggressive targets planned for the coming years. Lighter weight body structures promote reduced vehicle emissions. Fuel price increases lead to greater consumer sensitivity to vehicle fuel economy. […]| AHSS Guidelines
Automakers contemplating whether a part is cold stamped or hot formed must consider numerous factors. This blog covers some important considerations related to welding these materials for automotive applications.| AHSS Guidelines
Automakers contemplating whether a part is cold stamped or hot formed must consider numerous ramifications impacting multiple departments. Here, we'll focus on grade options and corrosion protection.| AHSS Guidelines
Contributed by Menachem Kimchi, Ohio State University Advance High-Strength Steels (AHSS) have been resistance welded in automotive production lines in the last few years. However, the high strength and hardness can be expected to affect spot weld failure modes during the typical peel testing and chisel testing performed for weld quality evaluation. A well-established industry […]| AHSS Guidelines
Steel, and specifically advanced high strength steel, satisfies automotive industry requirements for safety, emissions, fuel efficiency, manufacturability, durability, and affordability. Affordability The automotive industry has adopted light-weighting as a key part of their greenhouse gas reduction strategy. This strategy, however, must be executed in an affordable manner. Key reasons to deploy advanced high strength steels […]| AHSS Guidelines

Using Life Cycle Assessment, Mobility as a Service (MaaS) mobility solutions like WorldAutoSteel’s flaghip Steel E-Motive (SEM) program have the potential to contribute to a reduction in GHG emissions, helping to achieve these global targets and specific policy objectives.| AHSS Guidelines
Key materials characteristics for formed parts include strength, thickness, and corrosion protection. Tailored products provide opportunities to place these attributes where they are most needed for part function, and remove weight that does not contribute to part performance.| AHSS Guidelines

Martensitic steel grades provide a cold formed alternative to hot formed press hardening steels. Not all product shapes can be cold formed. For those shapes where forming at ambient temperatures is possible, design and process strategies must address the springback which comes with the high strength levels, as well as eliminate the risk of delayed fracture.| AHSS Guidelines
The Resistance Spot Welding (RSW) process is often used as a model to explain the fundamental concepts behind most resistance welding processes. If the sheets are steel, the resistance to the flow of current of the sheets will be much higher than the copper electrodes, so the steel will get hot while the electrodes remain relatively cool.| AHSS Guidelines
Resistance welding processes represent a family of industrial welding processes that produce the heat required for welding through what is known as joule (J = I Rt) heating.| AHSS Guidelines
Springback correction can take many forms. The first approach is to apply an additional process that changes the elastic stresses to a less damaging form. One example is a post-stretch operation that reduces sidewall curl by changing the tensile-to-compressive elastic stress gradient through the thickness of the sidewall to all tensile elastic stresses though the thickness.| AHSS Guidelines
AHSS products have significantly different forming characteristics and these challenge conventional mechanical and hydraulic presses. The dramatically higher strength of these new steels result in higher forming loads and increased springback.| AHSS Guidelines
