Heavy Manufacturing (Page 4)

We are pleased to welcome U.S. Pipe, a Forterra company, to EWI membership. Headquartered in Alabama, the company specializes in the manufacturing of a broad line of ductile iron pipe products, fittings, and joint restraints used in drinking water and wastewater systems.

While spot weld performance has become easy to simulate in recent years, failure models for arc-welded sheet steel have never proved very reliable. Recently, EWI developed and tested a new approach to modeling failure of arc welds used in sheet-steel construction. The work is described in a paper by EWI associates Bill Mohr and Amin...

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...
