Read MoreDesign of experiments (DOE) tools help manufacturers assess and develop processing technologies for a wide range of applications. DOE approaches allow users to develop empirical maps correlating input factors to selected process responses. These maps can then be used to optimize processes for quality and performance. There are several key steps in creating a DOE, […]
Read MoreSo, you’re assessing a processing technology for your manufacturing system. How do you characterize performance? What assessment tools can be used to make sure the fabrication process you develop will be scalable and efficient on the factory floor? Design of experiments (DOE) methodology offers a statistics-based approach for understanding the behaviors and responses of specific […]
Read MoreLow force friction welding, a technology developed jointly by EWI and Manufacturing Technology, Inc. (MTI), combines resistance-based pre-heating with a translational relative motion to create a joint. The process has been successfully tested on metals and metal-based alloys. One such study is reviewed in Low Force Friction Welds in 4130 Steel: A Preliminary Microstructural Characterization, […]

Read MoreFriction welding, a solid-state process that uses high-speed spindles to weld materials, is notably effective for joining dissimilar materials. EWI has recently developed a new micro-friction welder for small-scale, dissimilar metals joining. The system has been demonstrated on both aluminum-to-titanium and aluminum-to-stainless joints. Application of Micro-friction Welding for Dissimilar Metals, a paper by EWI’s Jerry […]
Read MoreIn battery manufacturing, foils are attached via ultrasonic metal welding, an effective method with some significant drawbacks. These include debris generation, fatigue and cracking, and difficulty with in-process monitoring. EWI has recently been working with an alternative joining technique for battery foils, capacitive discharge (CD) welding. Its advantages include rapid thermal cycling results, highly localized […]
Read MoreTechnology innovator EWI is pleased to introduce Manufacturing Technology, Inc, as its newest Strategic Technology Member. Together, EWI and MTI, a leading manufacturer of inertia, direct drive, and hybrid friction welders, will work in collaboration to advance the new hybrid joining technology known as low force friction welding. “Low force friction welding is a break-through […]
Read MoreVehicle lightweighting and crash performance are key – and often conflicting – goals of the automotive industry. Generation III advanced high-strength steels (AHSS) offer both strength and formability in a lightweight material, making them ideal for use in current model cars. Circumferential cracking of spot welds, however, has been observed with Gen III AHSS. This […]
