In brief
Avinash Tambewagh is Technical Head of TCR Engineering, a metallurgist with over 34 years of hands-on experience in advanced material testing, corrosion engineering, root cause failure analysis and foundry operations. He has specialised in technical support, laboratory administration and consultancy, and has helped national and international companies set up current-generation corrosion testing laboratories for sour service applications.
He works to national and international codes (ASTM, BS, EN, BIS, IS, ISO and NACE), connecting metallurgical science to industrial quality assurance.
Background and experience
He manages the advanced testing department, which runs High-Cycle Fatigue (HCF), Low-Cycle Fatigue (LCF) and Fatigue Crack Growth Rate (FCGR) evaluations. In fracture mechanics he runs testing programmes for plane-strain fracture toughness (KIC), elastic-plastic fracture toughness (JIC), and Crack Tip Opening Displacement (CTOD) at both ambient and sub-zero temperatures.
- Fatigue and fracture: high-cycle and low-cycle fatigue, and fatigue crack growth rate.
- Standards: ASTM E466, E606, E399, E1820, E647; BS 7448; ISO 12135 and ISO 15653.
- Sour service: NACE MR0175/ISO 15156, NACE MR0103/ISO 17945, NACE TM0177, TM0284 and TM0103.
- Named engagement: Accelerated Creep Rupture Testing per ASTM E139 and API standards for Saudi Aramco.
- Foundry background: melting, moulding, methoding and gating for corrosion and heat-resistant alloy steel castings.
- Certifications: ISO internal auditor, and ASNT Level II in UT and PT.
The work is run to ASTM E466, E606, E399, E1820, E647, BS 7448, ISO 12135 and ISO 15653. On that capability he has executed tailor-made testing programmes in fracture appearance, fatigue, and fracture toughness for strategic Navy and Defence projects.
In corrosion and chemical testing he works to the international specifications for material integrity in harsh environments: NACE MR0175/ISO 15156, NACE MR0103/ISO 17945, NACE TM0177, NACE TM0284, NACE TM0103, NACE TM0316 and ASTM G146 hydrogen induced disbonding (HID) testing, alongside the ASTM G-series (including B117, G28, G31, G36, G39, G47, G48, G66, G67, G78), ISO 3651-2, and GOST-6032. His corrosion work includes Four-Point Bend Sulphide Stress Cracking (SSC) Testing by the strain gauge method for Thai-Nippon Steel during their Myanmar Oil & Gas Project.
He also applies advanced test methods to engineering problems in the infrastructure, rail and energy sectors. He managed the Accelerated Creep Rupture Testing (ACRT) per ASTM E139 and API standards for Saudi Aramco’s Yanbu Refinery, utilising the Larson-Miller parameter and the Omega Method for a Remaining Life Assessment (RLA) study. Additionally, he has handled FCGR Testing per EN 13674 and ISO 12108 for Jindal Steel & Power Limited (JSPL) for railway track-rail applications, and routinely oversees slip testing for reinforcement bar couplers and mechanical splices under ASTM A1034, IS 16172, and ISO 15630.
His foundry background covers melting, moulding, methoding, and gating systems for specialised corrosion and heat-resistant alloy steel castings. He was recognised and rewarded at M/s. Kirloskar Brothers Limited (KBL) for reducing casting rejection rates for chemical-handling centrifugal pump impellers. That knowledge of manufacturing defects informs his work in Failure Analysis and Root Cause Analysis (RCA), where he diagnoses component failures for products sourced from aggressive environments like chemical plants, petroleum refineries, and active oil wells.
A certified ISO Internal Auditor holding ASNT Level II certifications in Ultrasonic Testing (UT) and Penetrant Testing (PT), he has organised, handled and cleared Second and Third-Party Inspections (TPI). He has steered plant integrity audits on behalf of MECON and routinely coordinates with owners, regulators, classification societies and their appointed inspection agencies, including LRIS, BVIS, IRS, NTPC, TOYO, ONGC, BHEL-CQS, TPL, QUEST, IL, ABS, Multitex, GESCO, DNV, TUV, NPCIL, BARC, EIL, Uhde, FEDO, IBR, L&T, IQC and HPCL.
