I. Parameter Setting Optimization
Temperature Control: Set preheating temperature, welding temperature, and time according to material type (e.g., metal/plastic) to ensure thermal stress balance. For example, metal printing requires adjusting laser power and scanning speed, while plastic welding requires controlling melting temperature.
Speed and Cooling: Reduce printing or welding speed, decrease cooling fan power, and enhance interlayer bonding.
II. Process Validation
Destructive Testing: Check if the weld strength reaches more than 80% of the base material, and the fracture location should be in the base material.
Non-destructive Testing: Use an infrared thermal imager to monitor the temperature field and ensure temperature uniformity (e.g., the ideal temperature for ABS material is 190-220℃).
III. Regular Maintenance
Cleaning and Inspection: Clean the welding table, transducer, and pneumatic system daily, and check weld head wear and connection tightness.
Calibration and Lubrication: Calibrate the printing platform level weekly, and check and lubricate the mechanical structure (e.g., guide rails, lead screws) monthly.
Software updates: Regularly upgrade device firmware and optimize parameters to match new materials.
