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...

Welding of dissimilar polymers is becoming more commonplace in manufacturing. There are several key reasons for this trend.  First, many new plastics are being used in environments where adhesives cannot be easily applied. Typical examples include medical products for which finding adhesives that pass FDA regulations and join materials with low surface energy (like polyolefins)...
