Weld inspection (ISO 9015)　

Automated Testing for Weld Zones, HAZ and Base Material

ISO 9015 requires hardness testing to be performed across multiple critical zones of a welded component to verify the mechanical integrity of the weld.

The IMPRESSIONS™ module simplifies this process by enabling:

• Fully automated weld hardness testing setup
• Predefined test points across the weld seam
• Hardness testing in the Weld Metal (WM)
• Hardness testing in the Heat-Affected Zone (HAZ)
• Hardness testing in the Base Material (BM)
• Automatic correlation and spacing of all test points
• Repeatable testing across multiple operators and samples

This ensures accurate and consistent hardness profiling across the complete weld cross-section.

Standards-Compliant Testing According to ISO 9015

The software is fully configured to perform weld hardness testing according to ISO 9015, the international standard covering destructive tests on welds in metallic materials.

This includes:

• Hardness traverses across weld cross-sections
• Verification of hardness values in critical weld zones
• Correct indentation spacing and test geometry
• Controlled positioning according to standard requirements
• Consistent documentation and result evaluation

Using predefined templates and automated workflows aligned with ISO 9015, the system reduces setup time and eliminates operator uncertainty.

This is especially valuable for laboratories performing frequent weld qualification and certification testing.

Automated Pattern Setup for Faster Weld Inspection

Manual weld hardness testing setup can be complex and time-consuming, especially when precise positioning is required across multiple weld zones.

The IMPRESSIONS™ Weld Hardness Module makes setup simple by using:

• Pre-set test patterns according to ISO 9015
• Automatic placement of test points in the correct weld zones
• Intelligent spacing based on standard requirements
• Automatic correlation between test rows and test positions
• Full integration with Pattern Editor and Edge Detection tools

This allows operators to perform complex weld hardness traverses quickly and with high confidence.

The result is faster testing, stronger repeatability, and reduced operator dependency.

Embedded Calculations and Hardness Profile Evaluation

The software automatically manages the full weld hardness test sequence and provides clear evaluation of the hardness profile across the weld.

A typical weld hardness traverse compares values across multiple zones:

Where:

• HVWM = hardness of Weld Metal
• HVHAZ = hardness of the Heat-Affected Zone
• HVBM = hardness of the Base Material

This allows fast identification of:

• Excessive hardness peaks
• Improper heat treatment effects
• Brittle zones in the HAZ
• Risk areas for cracking or failure

The system ensures consistent interpretation and repeatable results across all weld inspections.

Enhanced Reporting for ISO 9015 Compliance

The IMPRESSIONS™ Report Generator includes dedicated reporting templates specifically for weld hardness testing according to ISO 9015.

Reports can include:

• Sample identification and weld specifications
• Weld hardness traverse results
• HAZ, WM, and BM hardness values
• Pass / Fail evaluation according to customer or standard requirements
• Test pattern visualization
• Sample overview images and stitched images
• Optical measurement images and indentation records
• Statistical summaries and operator notes
• Customer-specific reporting requirements

This creates professional, audit-ready reports for certification, customer approval, and production quality assurance.

Applications of Automated Weld Hardness Testing

This module is essential for industries where weld integrity directly affects safety, compliance, and long-term performance.

Typical industries include:

Oil & Gas

• Pressure vessels
• Pipelines
• Offshore structures

Aerospace

• Structural welded assemblies
• High-performance alloy weld verification

Automotive

• Chassis components
• Safety-critical welded structures

Heavy Industry

• Crane systems
• Mining equipment
• Construction machinery

Energy Sector

• Power generation components
• High-temperature welded systems

In all these industries, accurate weld hardness testing is critical for preventing failure and ensuring compliance.

Automated vs Manual Weld Hardness Testing

Traditional manual weld hardness testing can be slow, difficult to position accurately, and highly dependent on operator skill.

IMPRESSIONS™ provides a far more efficient solution.

Manual Testing Limitations

• Manual positioning across weld zones
• Difficult spacing consistency
• Time-consuming pattern setup
• Increased risk of incorrect test point placement
• Manual calculations and reporting
• Reduced repeatability between operators
