MAC’s Weld Zone Profiler is designed to monitor the weld quality of a tube by depicting the “profile” of the completed weld. Unacceptable weld profiles can indicate potential problems associated with irregularities in the scarfing and trimming process, a reduction in the weld size, and other anomalies which compromise the performance of a welded tube.
This system incorporates our Echomac® FD electronics, with custom Echohunter® software for profile monitoring, ultrasonic test head mechanics, pillar and guide unit, 1 transducer providing 1 channel for wall/weld profile, downstream video monitoring, and an optional off-line calibration station.
- Pillar and gantry unit for support and stabililzation of test head.
- Special ride shoe to withstand harsh environments.
- Couplant for UT using bubbler technique.
- Custom designed test head scans the weld zone.
- A-Scan display of profile waveform and strip chart profile view, tracking and recording.
A robust pillar and gantry unit supports and stabilizes the transducer test head and positions it onto the weld line for mill testing, and off line for easy calibration of a new tube size. MAC’s custom-designed test head rides on the tube surface, oscillating back and forth across the weld area while performing the scan.
The transducer is mounted in a special ride shoe which is designed to withstand especially harsh environments and the sound beam is coupled to the tube through a short water column using the bubbler technique.
The Echomac® electronics and Echohunter software integrates a UT setup parameter panel, A-Scan display of profile waveform and strip chart profile view, tracking and recording all into a single program for ease of use. Production data can be saved and/or transferred to disc or Ethernet. Printing of setups, wave forms, or strip chart recordings can be done with the push of a button. Summary reports are given at the end of a production run containing the total number of pieces, length tested, number of rejects, time and date stamp, along with material and customer information.
