Critical Weld Evaluation Through Etching Techniques

Macro and Micro Etching are essential non-destructive metallographic methods used to evaluate the quality, structure, and integrity of welds and base metals. These techniques reveal welding profiles, grain boundaries, heat-affected zones (HAZ), and any internal inconsistencies such as lack of fusion, improper penetration, inclusions, or cracks.

At Qualitest Offshore, we perform etching services both in the field and laboratory settings, offering immediate, accurate results supported by detailed visual documentation.

Applications of Macro & Micro Etching

We provide etching services for:

• Welding procedure qualification (WPS/PQR)
• Welder performance qualification (WPQ)
• Inspection of weld cross-sections in fabrication yards
• Failure analysis of structural components and pipelines
• Material integrity evaluation in boilers, chillers, and heat exchangers
• Microstructure verification in duplex, carbon steel, and alloy materials

These methods are often used to verify welding standards, especially during construction, QA/QC audits, and mechanical testing programs.

Macro vs. Micro Etching – What’s the Difference?

• Macro Etching: Reveals the overall weld profile and structural flaws visible to the naked eye at low magnification. Ideal for assessing weld penetration, bead shape, and HAZ.
• Micro Etching: Uses microscopes and fine polishing to reveal microstructural details such as grain size, phase distribution, segregation, and microscopic cracks. It’s critical for detecting micro-level metallurgical inconsistencies.

Both are used together for a comprehensive weld quality assessment, especially in critical offshore fabrication and pressure-retaining applications.

Certified Technicians & Standard Compliance

Our inspections are carried out by trained professionals certified in welding inspection and NDT. We follow industry codes such as:

• ASTM E340 / E407
• AWS B4.0
• ASME Section IX
• ISO 17639

Our process includes sample cutting, preparation, etching, polishing, and thorough documentation with macro/micro photographs and interpretive remarks.
