      🔷 Direct Diode Laser Welding Machine
      This system uses diode laser light directly without laser crystals such as YAG or YVO4, delivering high electrical-to-optical efficiency and energy savings. It supports Active Heat Control® and is suitable for resin welding and laser soldering requiring precise heat control.

      🔷 Product / Technology Mechanism
      • The core technology is Active Heat Control®.
      • Laser output is controlled based on actual heat generated at the processing point.
      • Dedicated optics detect heat and provide real-time feedback.
      • Output is automatically adjusted to the preset heat level for stable processing.

      🔷 Differentiator / Why it Matters
      • Conventional systems control output based on internal machine values.
      • Workpiece-based control enables optimization aligned with material heat behavior.
      • Suitable for processes where heat input management is critical.
      • Also applicable to precision heating such as hardening and annealing.

      🔷 Application Capability
      • Laser Resin Welding
      • No adhesive required, improving recyclability and reducing environmental impact.
      • The direct diode laser in ML-5120A is suitable for low-melting-point resins.
      • Active Heat Control® ensures uniform weld quality without scorching.

      🔷 Laser Soldering
      • Supports a minimum focus diameter of φ0.2 mm.
      • Ideal for narrow areas or components that cannot be fully heated.
      • Compatible with lead-free solder.

      🔷 System Flexibility
      • Supports dual-branch optical systems operating simultaneously.
      • Enables two-point irradiation or two-line operation with one unit.
      • Improves equipment utilization rates.
      • Active Heat Control® operates only with a single optical path.
      • During branching, control is effective on one side only.

      🔷 Control & Monitoring
      • • Power Monitor included as standard.
      • • Allows high-precision monitoring of laser output.
      • • Supports process quality control and long-term stable operation.

      📘 Summary
      AMADA’s direct diode laser welding machine features precise heat control through Active Heat Control®, enabling high-quality resin welding and laser soldering. Flexible optical configurations and output monitoring support stable and precise production processes.
