When it comes to joining dissimilar materials in lithium-ion batteries, ultrasonic metal welding is fast and efficient. However, due to tool wear, the sonotrodes used in battery joining have to be completely replaced frequently. EWI has developed a new design approach that uses finite element analysis (FEA) to evaluate ultrasonic welding tools with replaceable knurl...

As interest in transitioning to hydrogen as a replacement for fossil fuels increases, there is a need to evaluate existing natural gas pipelines to see if they can be effectively retrofitted for safe, reliable hydrogen transport. EWI has established a joint industry program to conduct rigorous testing, close the knowledge gaps, and develop operator guidance...

Over the past several years, there has been great interest in developing ways to remotely execute critical manufacturing processes like welding, machining, and inspecting across long distances. In 2018, a joint research team led by EWI identified the challenge of creating a “tele-manufacturing” system that could do exactly that – enable workers to operate functional...
