Read MoreEWI is broadly recognized as an engineering consultancy that can help manufacturers solve their problems and improve their processes. Less well known is the fact that EWI has a robust internal R&D program aimed at developing innovations that advance the state of manufacturing technology overall. We’re pleased to announce that three recent projects were awarded […]
Read MoreThe integration of advanced high-strength steels in automotive body-in-white manufacturing has made vehicles lighter, improved crash performance, and reduced noise, vibration and harshness. However, the use of AHSS materials has also been correlated to spot weld cracking, especially with Gen 3 steel grades. EWI’s new H-coupon test was developed to assess the influence of gap […]

Read MoreEWI and MTI, developers of the new joining methodology low force friction welding, have continued a series of materials studies over the past year to qualify the new process for a variety of metals. A new paper by EWI Senior Technology Leader Jerry Gould, Application of Low Force Friction Welding to a 6061-T6 Aluminum Alloy, […]
Read MoreLow force friction welding, a hybrid technology developed by EWI and MTI, uses an external energy source to raise the interface temperature of the parts being welded, reducing process forces required to make a solid-state weld compared to traditional friction welding. Low Force Friction Welding of Bimetallics: Aluminum 6061 to 1020 Steel Tubes, written by […]
Read MoreSolid-state welding processes are a group of technologies in which joining is accomplished without melting the individual substrates. In these processes, bonding is accomplished by a combination of heating and forging. Heating is used to both lower the flow stresses enabling forging, as well as promote diffusion between the individual substrates. Common variations of these […]
Read MoreThe introduction of lighter and stronger metals in automotive design is an overall win for both manufacturers and consumers. The properties of these advanced materials, however, make crash performance modeling a challenge. EWI has developed a new solution for predicting crash behavior that can save automakers both time and money. Addressing the Role of Joints […]
