When the same defect reappears after every corrective action, the problem is no longer the defect itself, it is what is causing it. This article explains how to approach a repetitive failure in production systematically: from identifying its structural origin to validating the solution through laboratory testing, so that the problem does not come back.

A laboratory test is insufficient when the controlled conditions under which it is performed do not reproduce the real service loads acting on a component: combinations of mechanical stress, temperature, chemical agents and operational cycles that only occur simultaneously in the field. This is a recurring issue in sectors such as automotive, energy and the

Identifying the chemical composition of a material without destroying it, without preparing the sample, and without leaving the production floor is possible thanks to portable X-ray fluorescence. The XRF gun has become a reference tool in sectors such as automotive, metallurgy, construction, and recycling, where response time and material traceability are critical factors. This article

Fatigue fracture is identified by three distinct zones on the fracture surface: the initiation point (smooth, localized area), the propagation region with concentric beach marks visible to the naked eye, and the final fracture zone (rough, with a brittle or ductile appearance). Confirmation is carried out through fractography and SEM electron microscopy testing, which reveals

Detecting contamination in industrial processes at the right time is the difference between a manageable deviation and a service failure with economic and reputational consequences. Yet most industrial contaminants are not visible, produce no immediate signal, and in many cases originate from the process itself: equipment wear, batch carryover, secondary reactions, or material degradation. This

Lithium battery failures in industrial environments result from a complex interaction between electrochemical mechanisms, operating conditions and design factors. Identifying the root cause requires going beyond visible symptoms: it demands combining materials characterisation, electrochemical evaluation and knowledge of the actual operating context. At Infinitia, we analyse these failures through a multidisciplinary approach integrating engineering, chemistry

Evaluating the quality of an industrial component goes beyond checking that it meets a dimensional specification. It involves verifying mechanical properties, chemical composition, structural integrity, and behaviour under real operating conditions. In sectors such as automotive, energy, or aerospace, this verification combines standardised testing, under ISO, ASTM, or equivalent standards depending on the sector, with

A premature failure in an industrial component is one that occurs before the component reaches its expected service life under the operating conditions for which it was designed. The most common causes include manufacturing defects, mechanical overload, corrosion, material fatigue, and assembly errors. Identifying which of these factors, or which combination of them, has caused

An industrial failure investigation is the technical process by which the causes that have led a component, material or system to stop functioning according to its specifications are identified. It is structured in five phases: initial diagnosis, failure characterisation, root cause identification, experimental validation, and definition of corrective actions. At Infinitia we approach this process

Elemental analysis in materials makes it possible to identify and quantify the chemical elements present in a sample to understand its composition, detect deviations from specifications, and determine the origin of in-service failures. This article explains what techniques exist, when each one applies, and how to interpret their results in real industrial contexts. What is
