Diode lasers - a modern tool for welding processes; advantages and applications

While cutting is a major laser application, laser welding is gathering new applications day-by-day. The current diode laser technology supports ongoing process developments and improves existing welding applications. This is driven by low investment and cost of ownership, but now process results show incredible improvements concerning spatter, homegenous welds and adaptive in-situ process control.

In many applications diode laser technology is thought of as the legitimate successor of CO2 lasers. The presentation includes some application results to demonstrate the above, along with a general update on the current range of welding applications.
