Correct preparation of the framework before soldering
Successful high-fusing soldering of cobalt-chromium alloys depends on clean surfaces, accurate component fit and controlled heating.
Before heating
- Clean and prepare the metal surfaces to be joined.
- Check that the soldering area is free from contamination.
- Stabilise the components before heating.
- Apply a compatible flux according to the laboratory protocol.
During soldering
- Gradually heat the entire soldering area.
- Control the application of the Wirobond®-Lot solder rod.
- Avoid local overheating of the framework.
- Observe the flow of the solder over the prepared surfaces.
Laboratory recommendations for use
Wirobond®-Lot should be used by a professional trained in high-fusing dental soldering techniques. The choice of solder must remain compatible with the parent alloy and with the stage of framework fabrication.
- Check compatibility with the cobalt-chromium alloy being used.
- Select a flux suitable for the working temperature.
- Use an amount of solder appropriate to the size of the joint.
- Control the temperature to avoid damaging the components.
- Clean, inspect and finish the area after cooling.
For procedures requiring stable positioning, a soldering table can improve visibility and precision during the soldering procedure.
