Dana Corp.'s Driveshaft Div. has introduced a magnetic-pulse welding process for joining ferrous and non-ferrous material to form lighter, more compact--and in some cases--previously non-producible driveshaft configurations. "The process results in a metallurgical attachment that outperforms conventional MIG welding and competing mechanical attachment processes," says Jim Duggan, Dana's chief engineer of advanced design. The process creates an intense magnetic field by downloading large amounts of electrical energy into a specifically designed coil over a very short period of time. When an aluminum tube, for example, is subjected to the field, it collapses inward with sufficient force to weld itself onto a stationary component, such as a steel or aluminum shaft. The solid-state weld process requires no heat, with the component orientation controlled by machine tooling. FAX (419) 866-2616.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
