Corrosion is an inescapable, ongoing issue for most manufacturers. There are, however, different science-based options for preventing, detecting, evaluating, and mitigating corrosion. Josh James, EWI Principal Engineer and Research Leader, provides a concise overview of these approaches in his new paper, Corrosion Science: An Indispensable Tool Kit in All Manufacturing Development Stages. You are invited...

Qualifying very thick steel and new steels for use in construction, shipbuilding, pipes, and heavy equipment is not easy. Charpy tests are usually used, but the resulting data is not always consistent. Bill Mohr, EWI Principal Engineer for Structural Integrity, has conducted a study of crack specimens with splits. His work shows that Charpy and...

EWI recently completed a study which demonstrated the suitability of tandem/twin gas-metal arc welding for directed energy deposition (DED). Twin-wire pulsed technology offers a superior deposition rate, excellent feature fairness, and is tolerant to contact-tip-to-work variations. Because it is omni-directional with respect to travel direction and torchwire orientation, the process is compatible with robotic computer-aided...
