Design of Experiments (DOE) methods have been used as a tool for industrial research for many decades. These methods allow empirical correlation between defined input data factors and any number of responses from the process of interest. For example, in resistance spot welding input parameters might be current, weld time, and force. Responses would then […]
Read MoreAs manufacturers turn to multi-material designs to meet the ever-growing demands on their products, many are faced with the challenge of how to join dissimilar materials. Using traditional joining techniques, metallurgical incompatibilities of certain material combinations have greatly limited the performance and viability of many dissimilar joints. In order to achieve maximum performance from a […]

Read MoreThe joining aluminum and steel is encumbered by a range of metallurgical challenges including coefficient of thermal expansion and melting point differences, as well as the formation of deleterious intermetallics. Friction welding has demonstrated the capability to mitigate many of these challenges. When properly managed, friction welding facilitates …
Read MoreCandidate Friction Welding Methods for Joining Aluminum to Steel A new article by Jerry GouldEWI, Technology Leader The joining of aluminum to steel is of broad interest to manufacturers, but is plagued by a host of metallurgical problems. Friction welding offers unique potential for overcoming many of these concerns. This article provides examples of three […]
Read MoreIn October 2015, the EWI Forming Center hosted a well-attended Technology Workshop at EWI in Columbus, Ohio. The event provided a forum for industry experts to discuss current forming challenges for the manufacturing industry. Dr. Hyunok Kim, Director of the Forming Center, has written an overview of the center’s capabilities and initiatives and included a […]
Read MoreFABTECH is always an information-packed meeting for me. This year, advances in computer technology and information sharing capability was a strong theme with equipment suppliers. New types and improvements in welding consumables were also noteworthy. Welder training devices, including a couple that EWI helped to develop, were drawing crowds in several booths. EWI engineers had […]
