Microjoining encompasses techniques including welding, brazing, soldering, and adhesive bonding. Typically, the technology involves materials with thicknesses less than 0.5 mm. Micro-welding techniques can be applied to join both similar and dissimilar materials combinations. Here are some key applications of microjoining today: For over 30 years, EWI has been developing and applying microjoining technologies to […]
Read MoreSpringback is a critical challenge of forming and welding sheet metal parts for manufacturing applications in the aerospace, automotive, energy, electronics, and heavy manufacturing industries. Springback measurements can vary with material properties, stress-strain variables, part geometry, friction between forming tools, etc. It is difficult to eliminate springback during cold forming processes, but it can be […]
Read MoreInertia welding is a well-established, friction-based, solid-state joining process. Many different applications use this welding process, ranging from aircraft engine parts to air bag inflators to hand tools. Process parameters associated with inertia welding (spindle speed, welding force, inertia, and displacement) have been widely studied since the process gained traction in the late 1960s. One […]
Read MoreA few years ago, I wrote about the excitement of a new toy here at EWI. Since then, we’ve gotten several other new toys, but not one as close to my heart as the baby we just unwrapped! EWI recently took possession of a new Harms and Wende RPS100-K12 RFSSW machine! Woohoo! You have no idea […]
Read MoreThe Crazy Brilliance of Radio Frequency Welding When it comes to welding plastics, three contributing factors matter: heat, force, and duration. While there are multiple ways of controlling and applying each of these, the heating method defines the welding process: Welding Process Heating Method Vibration Surface Friction (linear) Spin Surface Friction (rotational) Hot Plate Conductive […]
Read MoreSo I’m not what you would call a handy person around the house and I generally pass on home projects unless forced to act. In fact I pretty much epitomize the quote “If a man says he will fix it he will. There is no need to remind him every six months about it.” I […]
Read MoreLightweighting is a process of replacing a material with another to reduce weight while maintaining performance. Automotive reduces weight to improve fuel efficiency primarily since the payload itself is fairly constant. Aerospace uses lightweigting to increase payload and range. In that respect, the advantage of lightweighting for heavy manufacturing is closer to that for the […]
