The new ExactWeld 430 from Coherent brings all the benefits of fibre laser welding to manufacturers of medical devices, electronic components, watches and other high-precision products.

It delivers high-strength, small seam size, cosmetically attractive welds at high speeds with minimal heat input. The system is easy to integrate into existing production lines and can be equipped with a robot interface for automatic part handling. ExactWeld 430 combines a fibre laser source, beam delivery optics, part fixturing, motion control, process gas delivery and an intuitive user interface in a compact, freestanding, Class-1 laser enclosure. It can weld virtually any metal and even join dissimilar materials.

The system’s working chamber is 500mm x 400mm x 200mm and incorporates a highaccuracy, three-axis, CNC linear motion system, and it is mounted on a solid granite base. This delivers exceptional stability and immunity from ambient vibration. The system can be configured with a variety of different Coherent fibre laser sources. These include StarFiber series products that can be operated either modulated or continuouswave, at average powers from 200W to 600W, making them ideal for high-speed conduction or keyhole seam welding. It’s also available with high-pulse energy models that are well-suited for spot welding and processing of heatsensitive parts.

These lasers are complemented with a complete selection of fixed focus optics and scanning heads to accommodate a very wide range of welding requirements. Amongst these are Coherent SmartWeld+ scanning heads – an advanced form of ‘beam wobble’ scanning that is particularly useful for heatsensitive materials and dissimilar material combinations
