AxSEAM 스캐너
반자동 AxSEAM™ 스캐너는 금속관에 대한 긴 용접부 검사를 용이하게 합니다. 스캔 속도와 접촉매질의 손실을 모니터링하고 스캔덱™ 모듈의 옴니스캔™ 장치에서 데이터 수집을 시작합니다. 간편하게 조정할 수 있는 프로브 홀더는 4개의 프로브를 지원하여 PA, TOFD 및 TFM 검사를 가능하게 합니다.
Overview
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
The AxSEAM scanner can scan longitudinal welds on pipes from 152.4 mm (6 in.) OD up to flat
Circumferential
With 2 probes, the AxSEAM scanner can inspect circumferential welds on pipes as small as 114 mm (4.5 in.) OD
With 4 probes, it can scan circumferentially on pipes starting at 254 mm (10 in.) OD [a 324 mm (12.75 in.) OD pipe is shown above]
Features
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
Other Key AxSEAM Scanner Features
- Patented dome-shaped wheels adapt to pipes without adjustment between changes in diameter
- Magnetic wheels and brake system to maintain the scanner position on the pipe
- Intuitive tool-free adjustment mechanisms and controls
- Convenient cable management sleeve
- 4 probe holders accommodating both PA and TOFD probes
