Detect internal weld defects
Porosity, lack of fusion, inclusions and cracks must be visible before the component moves forward.
Heavy engineering
Custom requirements. Engineered solution.
Inspect the Weld. Trust the Structure.
From straight pipe butt welds to SAW pipe joints, MQS engineers Digital Radiography solutions around the weld geometry, wall thickness, defect target, throughput and production environment.
Talk to an ExpertIndustry overview
Weld Quality Has to Hold Up in the Real World.
Heavy engineering depends on the integrity of welded pipes, tubular joints and fabricated structures. Porosity, lack of fusion, inclusions and cracks can remain hidden below the surface, while production teams still need fast decisions and consistent inspection records.
MQS develops Digital Radiography systems for weld inspection in production and quality environments, combining X ray sources, flat panel detectors, manipulation, shielding and imaging software into a system configured around the application.
Standard where it works. Custom where it matters.
MQS can start with a proven cabinet, bunker or modular architecture and configure the source, detector, manipulator, shielding, software and handling around the inspection requirement.
What heavy engineering QA teams need
What Heavy Engineering QA Teams Need from Inspection.
Handle changing pipe geometry
Diameter, wall thickness, material and weld location all influence the imaging setup.
Inspect at production speed
Real time imaging and repeatable manipulation help quality control keep pace with manufacturing.
Maintain consistent image quality
Source to detector geometry, positioning and software controls need to produce repeatable results.
Create traceability
Images, measurements and inspection records should support review, reporting and customer documentation.
Work to relevant standards
Inspection workflows need to align with the applicable weld and radiography requirements.
Application engineering
Your Weld Defines the Inspection.
The inspection system should follow the weld and production requirement, not the other way around. MQS starts with the pipe or component, the defect target and the workflow, then selects or configures the imaging and handling architecture.
Component & Weld
Diameter, wall thickness, material, weld type
Inspection Goal
Defect target, sensitivity, evidence needed
Imaging Chain
X ray source, detector and image quality
Handling & Shielding
Cabinet, bunker or modular integration
Engineered System

Indigenous engineering
Indigenous Engineering. Premium by Design.
For MQS, indigenization means design ownership, application engineering and the ability to adapt the complete system around the customer requirement. It is not a low cost positioning. The value is in engineering control, integration capability and long term support.
Deployment architectures
One Inspection Need. Three Ways to Deploy.
Cabinet Based Digital Radiography
Best suited for
Controlled inspection where a self shielded system fits the part size and workflow.
What MQS configures
Lead shielding, source and detector geometry, manipulator, interlocks and operator controls.
Bunker Based System
Best suited for
Larger parts, tubular weld joints or layouts where the inspection equipment operates inside a shielded room.
What MQS configures
Source and detector selection, manipulator, positioning, control station and bunker integration.
Open / Modular Integration
Best suited for
Existing shielded rooms or production cells that need a flexible inspection mechanism rather than a complete cabinet.
What MQS configures
Modular motion system, alignment, fixtures, automation and interface with the customer environment.

Inspection concerns
See the Defects That Matter.
The value of radiography is not simply producing an image. It is revealing the internal conditions that matter to weld quality and making them clear enough for a repeatable decision.
Porosity
Gas pockets and internal voids within the weld region.
Lack of fusion
Areas where weld material has not fused as intended.
Inclusions
Foreign or nonmetallic material trapped within the weld.
Cracks
Internal discontinuities that may not be visible from the surface.
Weld geometry and position
Image evidence that supports location, measurement and review of the inspected region.
Inspection evidence
Real Inspection Evidence.
MQS Imaging Suite
From Image to Evidence.
MQS Imaging Suite supports image acquisition, processing and review so operators can move from radiographic capture to a documented inspection decision within one workflow.
Dynamic & Static Imaging
Support live real time imaging and still image acquisition for detailed inspection.
Measurement Tools
Length, area and free hand measurements support dimensional review and documentation.
Automatic Enhancement
Image enhancement filters improve visibility and help operators review subtle indications.
Overlay & ROI
Compare images visually and focus analysis on selected regions of interest.
Detector Quality Tools
Bad pixel mapping, detector calibration, DIP calculation and SNR measurement support image integrity.
Standards Support
ASTM E2422 tools for digital radiographic detector validation and performance assurance.
Imaging That Supports the Decision.
The software layer matters because the same inspection must be repeatable across operators, shifts and customer reviews. Measurement, enhancement, detector validation and image comparison tools help convert radiographic data into usable inspection evidence.
Standards, safety & traceability
Built for Standards, Safety and Traceability.
ISO 17636
Weld inspection workflows reference ISO 17636.
ISO 10893-7 · ISO / EN 17636-2:2013
SAW pipe inspection references ISO 10893-7 and ISO / EN 17636-2:2013, with ASTM requirements where applicable.
ASTM E2422
MQS Imaging Suite includes ASTM E2422 tools for detector validation and performance assurance.
Radiation safety
System architecture can incorporate radiation shielding, interlocks, emergency controls and the safety provisions required for the selected installation concept.
Traceability
Digital images and software measurements support inspection records, review and traceability.
Proven platforms
Proven Platforms. Configured for Your Requirement.
Not every heavy engineering application needs a completely custom machine. Where a standard cabinet or manipulation platform fits the job, MQS can use it as the foundation. Where the pipe size, weld position, shielding concept, line layout or throughput requires something different, the system can be configured around the application.
Standard Platform
Best when the part size, source energy, shielding and handling requirement fit an established architecture. Configuration focuses on the application specific setup.
Custom Engineered Configuration
Best when geometry, line integration, bunker layout, manipulation, automation, fixtures or software workflow require a system designed around the customer environment.
