Microjoining

At EWI, our focus has always been on helping manufacturers solve real problems and move advanced technologies from concept to production. In 2025, that mission translated into meaningful progress across research, technology development, and knowledge sharing to support industries navigating increasingly complex technical and economic challenges. Throughout the year, our teams worked closely with partners...

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: Power electronics for electric vehicles (EVs). The integration of small-scale components, such as...

What are the best processes for joining miniature metal and plastic parts in commercial products? EWI has studied several techniques using different materials to determine effective microjoining solutions for manufacturers. This work is discussed in Plastics and Metal Joining: How Small Can You Weld?, a paper written by EWI associates Jeff Ellis, Miranda Marcus, Tim...
