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...

Directed energy deposition (DED), which leverages commercial robotic welding systems, is an agile and economical large-scale additive manufacturing (AM) process. DED AM is low risk since it leverages existing welding process equipment, consumables, procedures, and standards – which all have decades of proven performance. Using DED “digital” computer-aided manufacturing (CAM) software, component structures can be...

What are the best processes for joining miniature metal and plastic parts in commercial products? EWI has studied several techniques using different materials to determine effective microjoining solutions for manufacturers. This work is discussed in Plastics and Metal Joining: How Small Can You Weld?, a paper written by EWI associates Jeff Ellis, Miranda Marcus, Tim...
