The AWS Sheet Metal Welding Conference (SMWC XVIII) has announced its call for papers on the topic of “Welding Solutions for Lightweight Vehicle Production.” The conference, sponsored in partnership with EWI and ALAW, will be held October 17-18, 2018, in Livonia, Michigan. According to Jerry Gould, EWI Senior Technical Advisor and SMWC Technical Co-chair, topics […]
Read MoreOn October 19, EWI hosted an industry-wide workshop in Detroit to discuss current technical challenges in materials joining and metal forming. The underlying theme for the workshop was the recently completed NIST-funded Comprehensive Advanced Materials Joining and Forming Technology Roadmap, developed in concert with several joining and forming experts. One objective of the workshop was to […]
Read MoreDesign 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 […]
