Metallurgical Analysis

Processing of metal pieces affect the mechanical properties of that part. Heating, beating, foraging, casting, and welding all leave unique signatures in the final product. We have extensive experience performing the mechanical and metallurgical analysis required to tell the story of how an assembly was manufactured.

Corrosion Engineering

What starts as dust (ore) ultimately returns to dust (corrosion scale). Corrosion engineering services offer crucial solutions for combatting corrosion in challenging environments. Through risk assessment, material selection, and strategic maintenance, North Iron’s corrosion engineers protect infrastructure, prolong asset lifespan, and optimize operational efficiency. In house expertise includes electrochemical studies (TAFEL, Linear Polarization), design of cathodic and anodic protection systems, corrosion rate prediction, and corrosion mechanism investigations.”

Welding Inspections and Engineering

Welding is not the same as super glue. We provide welding inspection services and required associated non-destructive testing. NDT methods provided include ultrasonics (UT), mag particle (MT) and dye penetrant (PT) testing, hardness, ferrite and positive material identification (PMI) testing. Other welding related services provided include welding procedure specifications (WPS), procedure qualification records (PQR), and welder qualifications. Our in-house test lab can perform Charpy impact testing (CVN), tensile testing, bend testing, weld hardness surveys and NDT of weldments. Our expertise helps to ensure that welds and welding processes are code-compliant sound and secure.

Root Cause Failure Analysis

Equipment failures can have far-reaching consequences, often resulting in substantial financial losses and, in extreme cases environmental catastrophe or loss of human life. Understanding the root causes of these failures demands a comprehensive, multidisciplinary engineering approach. At North Iron Engineering, we specialize in failure investigation. Examples of destructive metallurgical techniques used by North Iron’s engineers include, optical metallography, scanning electron microscopy(SEM), energy dispersive spectroscopy (EDS), x-ray diffraction (XRD), x-ray florescence (XRF) and many others. Proper failure investigations not only uncover the immediate causes of failure but also provide insights crucial for preventing future incidents. Whether it’s a flaw in the manufacturing process or a recurring service issue, our approach ensures that every aspect of the problem is evaluated.

Asset Integrity Management

Maintaining the integrity of assets involves the coordination of corrosion engineering, nondestructive testing, project management, and risk analysis. We offer all of these, and have extensive experience managing asset integrity programs including API 653, API 570, and API 510.
