While spot weld performance has become easy to simulate in recent years, failure models for arc-welded sheet steel have never proved very reliable. Recently, EWI developed and tested a new approach to modeling failure of arc welds used in sheet-steel construction. The work is described in a paper by EWI associates Bill Mohr and Amin...

A standard electric vehicle (EV) automotive battery can be decomposed into cell level, module level, and pack level. A cell mainly includes the anodes and cathodes, a module includes multiple cells, and a pack includes multiple modules. The three most common metal-to-metal joints in a lithium-ion battery pack are foil-to-tab, tab-to-tab, and tab-to-bus. All three...

With an array of enhancements in recent years, laser welding offers many advantages as a joining process for automotive components. EWI Principal Engineer Eric Stiles has written Laser Welding for Automotive Electronics to present a range of advantages and applications of laser welding for vehicle parts and products.
