Acoustic Emission
VN500 Welding Control System Contacto
Detects and analyze spot and stud welding quality on the fly.
-Detects ultrasonic signatures in metal or piece and not current or voltages in welding machines.
-Analyze welding heating and cooling patterns.
-Decide "good" or "bad" welding with pre-programmed criteria.
-In accordance with the ASTM E751-1 standard.
-100 % spot or stud welding tested and very less destructive test.
-VN500 is based on Acoustic Emission techniques (see block diagram).
-VN500 detects automatically welding type spot or stud.
-Multiples simultaneous routines of ultrasonic signatures identification.
-Up to 256 different cycles of up to 256 welding each.
-Alerts operator with "Cycle ended" or "Change piece".
-4 digitals TTL digital outputs to control machines, devices or clamps.
-User or Supervisor mode.
-Fully programmable.
-Diary or periodic reports. VN500 can acts like data logger.
-RS232 Serial communication to PC for total logging or statistical analysis.
-Software to transfer data to spread sheets or other application.
-Autonomic for work island.
-Sensors for different materials and configurations.
