• Extensive metallurgical laboratory R&D experience with extensive hands-on experience of metallurgical sample preparation, microstructure characterization and root-cause analysis of the role of microstructure on the failure analysis of steel in H2S environment.
• 5+ years hands-on metallurgical characterization techniques of X-ray Diffraction (XRD), Optical Microscope (OM), Scanning Electron Microscope (SEM), Energy-dispersive Spectroscopy (EDS) and Electron Back-scattering Diffraction (EBSD), etc.
• Strong understanding of steel making process, pipeline forming process, rolling and heat treatments.
• Extensive knowledge of welding metallurgy and method in pipeline steel. Corrosion (Electrochemistry)
• Fundamental understanding of corrosion thermodynamics and investigation of the role of corrosion due to acidic environment in crack initiation and propagation in welded steel.
• Hands-on experience of cathodic charging, corrosion evaluation and failure analysis of parameters that drive crack initiation and propagation in oil and gas pipelines
• Investigated the role of corrosion in crack initiation and propagation in a spiral welded steel.
• Investigated the role of microstructure in pipeline susceptibility to hydrogen embrittlement. Materials Testing
• Hands-on experience of mechanical testing like tensile, compression, impact, bending, micro and Macro-hardness, etc.
• Expert in interpreting microstructural and fractographic interpretation for determine different failure modes during tensile, torsion and impact testing of steels.
• Experience of non-destructive testing like visual inspection, ultrasonic testing of welds in pipeline steel
• Hands-on experience in residual stress mapping and measurement in pipeline welds
• Evaluation of the impact of welding residual stresses on welded pipeline performance during field installation
• Root-cause analysis of failure in steel under different load conditions.
