A precise heat treatment is often a prerequisite when processing workpieces that will have a high load and a lightweight construction. Here, laser hardening allows the creation of a much more precise and more defined joint structure along the edges when compared to conventional methods. The key is that the heat treatment takes place under strict temperature control. This high precision is possible when you use our RLH-A. You can also define how wide the trace for the heat treatment should be. A built-in, rapidly moving mirror makes this possible.
