Metallurgical Engineering


This grouping of MegChem is represented in Secunda, Centurion and Durban and specializes in services related to the materials of construction and its degradation. Our staffing consists of approximately 15 engineers and technical staff and we are active in the petrochemical, power, construction, manufacturing and legal sectors locally and globally. We utilize our own well equipped laboratories and also perform metallurgical testing on site.

Metallurgical Engineering is the study of the internal structure and engineering behaviour of metals and engineering materials. Metallurgical knowledge is applied to study the structural strength, deformation behaviour, failure and environmental interaction of in-service engineering components.

A comprehensive metallurgical consulting service encompassing all aspects of Physical and Mechanical metallurgy, materials engineering, welding and corrosion, is supplied by MegChem.

A team of experienced metallurgical experts are supported by a well equipped metallurgical laboratory and certified testing facility, enabling MegChem to provide a one-stop metallurgical service to the petrochemical, mining and manufacturing industries, ranging from advanced failure investigations and Asset Integrity Management studies to basic material testing and certification. Due to our close co-operation with the petrochemical industry, specialist capabilities in the field of corrosion engineering, testing and monitoring, as well as plant integrity assessment and Risk Based Inspection were developed.


MegChem’s metallurgical division is a one stop solution for welding engineering services. Welding engineering involves the development of welding techniques, procedures and the application of welding knowledge in the solving of and optimizing manufacturing and welding related challenges.

Welding expertise in the form of weld related failure and forensic investigations as well as services for the design and approval of welding procedures is provided by MegChem. MegChem also has PQR testing capabilities, making MegChem’s metallurgical division a one-stop solution provider for welding services.

MegChem Forensic Engineers provide expert engineering services to the insurance companies, law firms and manufacturers. The forensic engineer meticulously investigates accidents and failures with the objective of establishing causation and the sequence of events leading to the accident. This work is then utilized by the legal profession for both civil and criminal court proceedings.

Forensic Engineering is primarily concerned with the correct reconstruction of an incident which resulted in failure, loss, injury or death. As such, Forensic Engineering is also often utilized in investigations with a commercial or industrial focus. Engineering knowledge, concepts and techniques are used in order to arrive at the required reconstruction.

The Team

In performing the forensic reconstruction the MegChem multi-disciplinary engineering team combines specialized knowledge and systems in the fields of materials behaviour, stress and structural analysis and failure, to arrive at the correct reconstruction. In doing so, they utilize state-of-the-art techniques and software, draws on the extensive experience of its staff. Our Forensic Engineers are supported by fully equipped Material and Mechanical testing laboratories. As a consequence, we often provide testing services, failure simulations through finite element modeling, reconstruction of failure reports and expert testimony following industrial incidents. These investigations have included failure and collapse investigations as well as fire and explosion investigations.
