Sigma Industrial Services has wide experience in Metallurgical testing in South Africa providing high quality analysis and accurate reports.

The unit comprises of young experienced and dynamic metallurgists who are eager to learn. The experience of our metallurgists covers a wide spectrum of physical and welding metallurgy. The unit offers the following services:

Replica Metallography

Failure Analysis/ Investigation

At a certain point in time during in-service, even the best material fails. There are many factors that may contribute to component failure. Our Metallurgists are capable of performing failure analysis and investigations in order to report the cause of failure. A number of failures can be attributed to failure mechanisms that include but not limited to fatigue, creep, stress cracking corrosion, etc.

Weld Fracture Test

Welding Procedure Qualifications

Welding is a critical joining process that requires stringent regulation and monitoring. As such, welders and procedures that are to be used for specific project should be qualified prior to the commencement of the project.
Our qualified International Welding Technologist and Metallurgists have the know-how on how to develop the Welding Procedure Specification (WPS).

Micro & Macro Examination

Hardness, Bend, Impact & Tensile Test

Positive Material Identification

Positive Material Identification (PMI) is one of the more specialised NDE methods. PMI serves critical roles in instances where material certificate is missing or it is not clear what the composition of a material is. This method can be used on ferrous and non-ferrous alloys in order to identify, detect and quantitatively measure elements such as Ti, V, Cr, Mn, Iron, Co, Ni, Zr, Se, Nb, Sn, Cu, Pb, Ta , etc
