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...

Combining aluminum and steel construction in vehicle manufacturing can offer great lightweighting and strength advantages. The formation of brittle intermetallic compounds (IMCs) in the joints between the materials, however, are known to impair performance.  Prediction of such intermetallic formation is often difficult to assess due to the rapid thermal cycles involved. A new technique for...

EWI is pleased to announce the receipt of three research awards from the National Shipbuilding Research Program (NSRP) as part of its continuing mission to reduce costs associated with U.S. shipbuilding and ship repair. The funded EWI projects include: PortableSingle-Pass Buried Arc Welding of Steel Plate During Ship Erection HighProductivity Reduced Emissions Arc Gouging Process...
