Eliminating the Heat-Affected Zone

Heat is energy transfer from one location to others. How much and how quickly the energy is transferred is determined by the material’s properties: thermal conductivity, heat diffusivity, etc. Generally, metals h…

What Does Cold Ablation Really Mean?

By | Blog | No Comments

The ablation process is the underlying mechanism for laser machining. Conventional pulsed-laser machining techniques dissociate matter at atomic and molecular levels via the deposition of laser radiation. The absorbed laser energy is transferred to t…
