Shipbuilding

If you are interested in EWI’s latest R&D for applied manufacturing, you can hear about it directly from our engineers throughout the month of March. EWI specialists will share new findings and applications at the following public forums and conferences over the next several weeks: LaMorte Women in Welding Virtual Conference, March 16, 2023 –...

Shipyards typically use submerged arc welding (SAW), flux cored arc welding (FCAW) or gas metal arc welding (GMAW) to fabricate butt joints in thick steel plate. But there are drawbacks to these traditional welding methods, such as the necessity for weld joint preparation. In addition, multiple welds are often required to fill the joint. Now,...

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...
