Inspection, testing & qual ity control

B-scan inspection system SCRAP reduction is of particular importance to the welded tube industry; relatively small reductions in percentage scrap can yield large savings. For tube manufacturers, monitoring the weld flash removal process on line well before problems are revealed at cut-off is an attractive scrap reduction tool, particularly when post-weld heat treatment imposes long cooling runs before cut-off. that have made the IBIS more user-friendly and flexible. In addition, the HMI (human-machine interface) has been updated and improved. The test head of

the IBIS flash monitor scans across the weld zone and adjoining parent metal covering a band around 50mm wide. The ultrasonic system makes thousands of readings during each sweep, measuring both the material thickness and the outer surface profile.

The InspecTech B-scan Inspection System (IBIS) was first sold to the welded tube industry more than 20 years ago. The unit was conceived and engineered around the ‘need to know’ the condition of the inside flash removal process, and the resulting scrap reduction potential. As computing power has increased, the performance and utility of IBIS have improved. Displays, once delayed, have moved to real-time, and the OD profile of the tube has been included on the screen in addition to the thickness scale. InspecTech has announced new software and firmware enhancements

company states that this would not be practicable in polar views.

Rather than a curved profile, IBIS displays a set of Cartesian plots that are calibrated directly in engineering units (inches or millimetres), and which may be used to define alarm limits and display allowable tolerances. The
