Four Steps to Mitigate Liquid Metal Embrittlement When Welding Steel
Liquid Metal Embrittlement (LME) during Resistance Spot Welding (RSW) can cause cracks when welding advanced high strength steels. Recent advances in steel metallurgy, resistance spot welding processing and accompanying simulation tools have substantially improved the...
Tensile Testing: Engineering Stress-Strain Curves vs. True Stress-Strain Curves
Tensile testing is one of the most basic formability characterization methods available. Results from tensile testing are a key input into metal forming simulations, but if the right information isn’t included, the simulation will not accurately reflect material behavior. Metal forming simulation is particularly beneficial on the value-added parts made from advanced high strength steels, since accurate simulations allow for optimal processing with minimal recuts … at least when the right information is used as inputs.
Resistance Spot Welding with Advanced High-Strength Steels: Cold Stamped and Hot Formed
The discussions relative to cold stamping are applicable to any forming operation occurring at room temperature such as roll forming, hydroforming, or conventional stamping. Similarly, hot stamping refers to any set of operations using Press Hardening Steels (or Press...
Cold Stamped or Hot Formed? Part II
Grade Options and Corrosion Protection Considerations When Deciding How A Part Gets Formed Automakers contemplating whether a part is cold stamped or hot formed must consider numerous ramifications impacting multiple departments. Our prior blog on this topic...
