AxSEAM

AxSEAM Semiautomated Scanner for Longitudinal Seam Weld Inspection

Optimized for long seam weld inspection, such as in electric resistance welded (ERW) pipes, the AxSEAM™ scanner’s simple design minimizes the number of adjustments required when changing pipe diameters, probe separation, or scan orientation.

An operator can set up and perform the scan independently without needing to manipulate or monitor the data acquisition instrument thanks to the innovative ScanDeck™ module. The redesigned, easily adjustable probe holders support up to four phased array (PA) and time-of-flight diffraction (TOFD) probes.

Versatile Multitechnology Solution When used with the OmniScan™ X3 flaw detector, the AxSEAM scanner enables fast PA/TOFD screening of long seam welds followed by more targeted inspection of regions of interest using the total focusing method (TFM)—without needing to switch the probes. TFM provides even focus in the region of interest, making it easier to characterize the difficult-to-detect indications that are typical in ERW long seams, such as vertical flaws and hook cracks.

Flexible Configuration

The AxSEAM scanner offers a complete scanning system, requiring only minor adjustments to switch between longitudinal and circumferential scanning on pipes.

Longitudinal

Circumferential

ERW longitudinal seam UT weld inspection scanner performing a circumferential scan on steel erw tubing With 2 probes, the AxSEAM scanner can inspect circumferential welds on pipes as small as 114 mm (4.5 in.) OD

Redesigned Probe Holder

To help ensure easy probe and wedge manipulation, stable probe positioning, and constant coupling, our innovative probe design includes:

Toolless probe switching
Adjustable to different wedge sizes
Vertical latching system to ease probe and wedge changes and handling
Adjustable pressure for the wedge on the pipe’s surface

Control Data Integrity with the ScanDeck™ Module Positioned in your line of sight, the ScanDeck™ module provides practical indicators and functions that enable you to focus on scanning: Monitor your scanning speed and coupling to help prevent missed data on the OmniScan X3 instrument “Zero” the connected encoder and start the acquisition on an OmniScan instrument (any model) Activate the laser guide to keep aligned with the weld line or markings
