Dissimilar metals joining is at best difficult and often impossible to achieve with traditional fusion methods.
Resistance welding and solid-state processes have proven to be the most successful in joining dissimilar materials.
EWI specializes in all types of resistance and solid-state welding. With broad expertise in materials science and controls engineering, we are able to be proactive in the face of new material joining challenges. Organizations often come to us with these goals in mind:
- Join difficult material combinations
- Develop tailored metallurgical properties, such as locally softening materials without sacrificing strength
- Develop customized repair technology
- Accomplish all goals in a timely, resource-conscious manner
Joining Solutions from a Dedicated Partner
EWI’s broad resistance and solid-state welding capabilities have made us a trusted partner for organizations in industries like automotive, aerospace, rail, and oil and gas. Much of that trust, however, comes from our ability to help throughout the development of a new production process, from tailoring technology to developing/executing design-of-experiment (DOE) methods. We use physics-based modeling to simulate conditions, set process parameters, and make sure the solution we provide is customized for the best outcome.
Our Welding Expertise in Action
EWI works to stay ahead of ever-changing market demands and technological advances. We’re proud to have developed resistance welding processes like these automotive industry examples:
- Developing in-situ heat treatment that allowed automakers to use advanced high-strength steels
- Integrating state-of-the-art prediction methods for assessing vehicle crash performance, which ultimately reduced physical testing requirements and enhanced product times to market
- Determining ideal local thermal processing procedures to tailor microstructures in critical sheet-metal components, which increased overall product safety and allowed a wider range of base materials
Other new innovations we’ve developed include conductive heat welding, resistance hole repair, and resistance pipe cladding.
