Since introducing its new VDA tight radius testing capability with digital image correlation (DIC) in Winter 2021, the EWI Forming Center has conducted further research test applications of the test on a variety of high-strength materials. A recent study evaluated test switch-off criteria and applied the results in finite element analysis (FEA). This work is...

EWI has recently developed a new method for joining thick steel plate by combining the hybrid laser arc welding and the submerged arc welding processes. The new approach is an improvement over earlier methods on many fronts, and further research is planned to test different materials and thicknesses. This project is discussed in Co-processing of...

Recently, EWI conducted a study in which ultrasonic vibrations were applied to the wire drawing process to improve both final wire quality and process performance. This investigation demonstrated positive results in several areas including wire roughness, dimensional accuracy, microstructure, draw force, and strength. It also reduced the number of die passes required to complete the...
