Rosie Matthies examines her welding handiwork in the EW microjoining lab EWI recently hosted two secondary school teachers as part of the Ohio STEM Learning Network’s Manufacturing & Engineering Externship Program (MEEP). Mary Tugend of Metro Early College Middle School (Columbus) and Rosie Matthies of Shawnee High School (Springfield) spent two days shadowing engineers and...

How can you control or compensate for springback in stamped parts when using new, advanced high-strength sheet metals? EWI has recently developed a specialized tool that is capable of assessing springback behavior without any wrinkling or necking on the tested part. The work is described in S-rail Test Tool for Evaluating Springback with High-strength Aluminum...

Metal matrix composites (MMCs) have always been considered “unweldable,” and have been joined mechanically in the past. Now, however, EWI reports that aluminum MMCs can be joined using friction stir welding, a solid-state joining method. This investigation is discussed in Friction Stir Welding of Metal Matrix Composites, written by EWI Senior Engineer Michael Eff. You...
