Summary
Manufacturing engineers often struggle using lasers to join materials that are relatively new to automotive components. Expanding laser technologies to broaden the horizons in laser applications has allowed for more materials to be processed, but sometimes introducing new difficulties. For example, copper is a highly-reflective material that does not easily absorb laser light, causing it to be relatively difficult to weld. Put simply, more laser light being applied to the material is needed to create these welds at the desired penetration depths. But this simple approach has led to problems of increased weld spatter and porosity. Laser manufacturers have relatively recently developed a solution that provides depth of penetration and aesthetically pleasing welds using a ring-core laser shape.
This is where a ring mode laser conditions the material being joined and the core provides the needed depth of penetration.
- What do we know about the ring-core mode and how is it best applied in a production environment?
- What does the ring-core mode have in common with other high-powered industrial lasers?
- And what unique performance characteristics do they have?
