8.4.2 Quality assurance
- Optical monitoring of the position of the applied adhesive
- Optical monitoring of the shape of the applied adhesive
- Distance control using sensors, e.g. for bonded hemming flanges
- Constant processing temperature (Recommendation: somewhat above the maximum temperature expected at the workplace; heed the manufacturer’s information regarding the max. processing temperature; position the plant in a temperature-controlled room; heated hoses/tubes)
- Adhesive – monitor the volume flow (directly or indirectly via temperature or pressure measurement)
- Regularly check the delivery rate; for 2-C adhesives check the mixing ratio
