The ExactWeld 430 from Coherent is a ready-to-use and easy-to-operate fiber laser welding machine that is ideal for prototyping and small- to medium-batch production. The machine brings all the benefits of fiber laser welding, delivering high-strength, small seam size, cosmetically attractive welds at high speeds with minimal heat input to the workpiece. The system is easy to integrate into existing production lines and can optionally be equipped with a robot interface for automatic part handling.
The ExactWeld 430 combines a fiber 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. The result is a machine that’s simple to set up and operate, and which can weld virtually any metal. It can even join dissimilar materials.
The ExactWeld 430 can be configured with a variety of different Coherent fiber laser sources, enabling it to be optimally matched to each user’s unique welding processes, materials and budget. These include StarFiber series products that can be operated modulated or CW at average powers from 200 W to 600 W, 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 heat-sensitive parts.
The ExactWeld 430 is an all-in-one, self-contained welding solution that can be running production parts almost immediately after installation. Coherent Labs can further support this by developing process recipes for specific welding needs in advance of delivery. And, the lab can provide new recipes if part specifications or configurations change.
- The system’s working chamber is 500 mm by 400 mm by 200 mm and incorporates a high-accuracy, 3-axis, CNC linear motion system. A rotary axis is an available option.
- Both the motion and laser systems are mounted on a solid granite base. This delivers the ultimate in stability and immunity from ambient vibration and ensures the accuracy of the precision motion system.
- There are several other options, including vision systems for alignment and pattern recognition.
- The lasers are complemented with a complete selection of fixed focus optics and scanning heads to accommodate a wide range of welding requirements.
- Coherent SmartWeld+ scanning heads are an advanced form of “beam wobble” scanning that is particularly useful for heat-sensitive materials and dissimilar material combinations.
