EWI Diagnostic Tools

Combining video with data acquisition programs can deliver a highly sophisticated tool for diagnosing potential problems and making adjustments while fabrication is in process. There are existing high-speed camera (HSC) and data acquisition (DAQ) systems that have been custom-built, but to-date these have been cumbersome to operate and commercially unsupported. EWI has developed a new,...

The H-coupon test, developed a few years ago to evaluate cracking behavior in spot-welded advanced high-strength steels (AHSS), has recently been applied to galvanized third generation AHSS. Two types of cracking have been observed in the tests of these steel grades – interfacial and zinc liquid metal embrittlement (LME). This research is discussed in Application...
