Areas of Expertise

Welding Engineering

Welding integrity is frequently central to engineering disputes involving fabricated structures, pressure-retaining systems, pipelines and industrial plants. Because welds form critical joints within engineering systems, issues relating to welding procedures, workmanship, material compatibility, heat treatment and weld repairs can have significant implications for structural integrity and operational reliability.

AHB provides technical analysis across the full lifecycle of welded fabrication. This may involve reviewing welding procedures, welder qualifications, fabrication records, inspection data and post-weld heat treatment processes to determine whether welding work has been performed in accordance with recognised engineering standards and project specifications.

Where failures or disputes arise, welding engineering analysis can help determine whether defects originated during fabrication, whether repair strategies were appropriate, and whether welding and inspection practices met the requirements of applicable codes and contractual standards. This expertise supports forensic investigation of failures, technical advisory work on complex projects, and the preparation of expert evidence in engineering disputes.

Metallurgy

The behaviour of engineering materials is often central to understanding why components fail or degrade in service. Questions relating to material selection, heat treatment, mechanical performance and microstructural behaviour frequently arise in engineering disputes and failure investigations, particularly where components operate under demanding environmental or mechanical conditions.

AHB analyses metallurgical evidence to assess how materials have performed within engineering systems and whether material behaviour contributed to the issue under investigation. This work may involve reviewing material specifications, manufacturing processes, heat treatment records, and service conditions to determine whether materials were suitable for their intended application and whether their properties were affected during fabrication or operation.

Metallurgical analysis can play a critical role in determining the causes of engineering failures, evaluating the progression of material degradation and assessing whether engineering materials met the requirements of project specifications and applicable standards. This expertise supports forensic investigation of failures, technical advisory work on complex projects and the preparation of expert evidence in engineering disputes.

Corrosion and Degradation

Corrosion and material degradation are among the most common causes of failure within industrial systems. In many engineering environments, materials are exposed to conditions where moisture, chemicals, temperature variations, or process fluids can progressively weaken structural components. Understanding how corrosion develops and how it interacts with materials and operating conditions is, therefore, often essential when investigating engineering failures or assessing the integrity of industrial assets.

AHB analyses corrosion behaviour within engineering systems to determine how degradation has occurred and whether corrosion mechanisms contributed to the issue under investigation. This may involve examining environmental exposure conditions, reviewing material selection, assessing protective coatings and corrosion protection systems, and analysing inspection and maintenance records to understand how deterioration progressed over time.

Corrosion analysis can be critical in determining the causes of equipment failure, assessing the adequacy of corrosion management strategies and evaluating whether materials and protective systems were appropriate for their operating environment. This expertise supports forensic investigation of failures, technical advisory work on complex projects and the preparation of expert evidence in engineering disputes.

Non-Destructive Testing (NDT)

Non-destructive testing plays a critical role in verifying the integrity of engineering systems without damaging the components being inspected. Inspection techniques such as ultrasonic testing, radiography, magnetic particle inspection, and other methods are widely used to identify defects in welded joints, fabricated structures, and pressure-retaining systems during both construction and service.

Disputes frequently arise where questions are raised about whether appropriate inspection techniques were selected, whether inspections were carried out correctly, or whether defects should reasonably have been detected. In such cases, the effectiveness of the inspection regime and the interpretation of inspection results can become central technical issues.

AHB provides independent assessment of non-destructive testing methodology, inspection planning and interpretation of inspection data. This may involve reviewing inspection procedures, evaluating technique selection, analysing inspection records and assessing whether inspection practices complied with applicable codes, standards and project specifications.

Understanding the capabilities and limitations of inspection techniques is often essential when determining whether defects originated during fabrication, whether inspection regimes were adequate, and whether inspection findings were interpreted correctly. This expertise supports forensic investigation of engineering failures, technical advisory work on complex projects and the preparation of expert evidence in engineering disputes.

Quality Assurance & Quality Control

Quality assurance and quality control systems are fundamental to ensuring that engineering work is carried out in accordance with project specifications, contractual requirements and recognised engineering standards. Within complex engineering projects, quality assurance establishes the framework of procedures, standards and documentation that govern how technical work must be performed.

Quality control verifies that framework. Through inspection, testing and review of project records, QC processes confirm whether fabrication, installation and inspection activities have been carried out in accordance with the requirements defined by the quality system.

Disputes frequently arise where questions are raised about whether quality systems were properly implemented or whether inspection and verification processes were adequate. In such cases, the technical issues often extend beyond the physical condition of a component to include the effectiveness of inspection and test plans, the completeness of project documentation and the traceability of materials, procedures and inspection results throughout the supply chain.

AHB provides an independent assessment of quality assurance and quality control systems across engineering projects and industrial facilities. This may involve reviewing inspection and test plans, fabrication documentation, quality management procedures and project records to determine whether appropriate engineering governance was implemented and whether technical work was carried out in accordance with applicable standards and contractual requirements.

Because QA/QC systems underpin activities such as welding, materials verification, corrosion management and non-destructive testing, understanding how these systems operate is often essential when analysing engineering failures or evaluating technical compliance within projects. This expertise supports forensic investigations of failures, independent technical advisory services during complex engineering projects, and the preparation of expert evidence in engineering disputes.

Fabrication and Manufacturing

Fabrication processes form the foundation of many engineering systems, particularly in sectors such as energy, infrastructure, pipelines, and industrial plants. The integrity of fabricated structures depends on the correct interaction of materials, welding procedures, heat treatment, inspection regimes and quality control processes. Where deficiencies occur within fabrication activities, the consequences can include structural defects, premature material degradation or failure of critical components.

AHB assesses fabrication practices across workshops, construction sites and supply chains to determine whether fabrication activities have been carried out in accordance with recognised engineering standards and project specifications. This work often involves reviewing manufacturing inspection and test plans (ITPs), fabrication procedures, inspection records, and quality documentation to understand how components were produced, inspected, and verified throughout the manufacturing process.

In many disputes, the technical issues extend beyond the physical condition of a component to include how fabrication activities were controlled and documented. Matters such as non-conformance reports (NCRs), technical queries (TQs), concessions, inspection records and material traceability can be critical in determining whether fabrication work complied with contractual requirements and recognised engineering practices.

AHB also evaluates the control and handling of materials, welding consumables, shielding gases and other critical fabrication inputs, as well as the storage and traceability systems used throughout the supply chain. These factors often play an important role in understanding how fabrication quality was managed and whether appropriate engineering controls were implemented.

Because fabrication integrates multiple technical disciplines, including welding engineering, metallurgy, corrosion protection, non-destructive testing and quality assurance systems, understanding fabrication processes is often essential when analysing engineering failures or evaluating technical compliance within complex projects. This expertise supports forensic investigation of failures, independent technical advisory during project delivery and the preparation of expert evidence in engineering disputes.

Damage and Failure Mechanisms

Engineering systems operating within industrial environments are often exposed to conditions that can progressively degrade materials and structural components over time. Damage mechanisms such as fatigue, corrosion-assisted cracking, thermal stress, creep, erosion or environmental degradation may develop gradually during service, sometimes remaining undetected until significant deterioration has occurred.

Understanding how these mechanisms initiate and progress is often essential when assessing the integrity of engineering systems or determining the causes of failures. In many cases, damage does not arise from a single isolated issue but from the interaction between material properties, fabrication processes, operating conditions and environmental exposure.

AHB analyses the mechanisms that drive material degradation and structural deterioration in engineering systems. This may involve examining service conditions, reviewing inspection and maintenance records, evaluating material behaviour and assessing how factors such as welding processes, fabrication practices and corrosion exposure may have influenced the progression of damage.

Where components have failed, assessment of the failed parts themselves can provide critical evidence. Examination of fracture surfaces and damage patterns may reveal whether failure occurred through brittle fracture, ductile overload, fatigue cracking or progressive degradation over time. These observations, combined with analysis of materials behaviour and operating conditions, help establish how damage developed and whether the progression of deterioration was consistent with expected service conditions.

Because damage mechanisms frequently involve the interaction of multiple technical disciplines, including metallurgy, corrosion behaviour, fabrication practices, inspection regimes and quality management systems, identifying the underlying causes of deterioration requires integrated technical analysis. This expertise supports forensic investigation of engineering failures, independent technical advisory work during complex engineering projects and the preparation of expert evidence in engineering disputes where the progression of material damage is central to the technical issues under consideration.

Structural and Pressure Retaining Systems

Structural and pressure retaining systems form the backbone of many engineering assets, from bridges, buildings, and large infrastructure projects to pipelines, storage tanks, pressure vessels, boilers, pipework systems, and industrial process facilities. Failures or disputes involving these systems can have significant safety, operational, financial, and contractual consequences, making independent technical assessment essential.

Engineering disputes frequently arise where questions are raised regarding structural integrity, design suitability, fabrication quality, material performance, inspection effectiveness, maintenance practices, or compliance with applicable codes, standards, and project specifications. In many cases, understanding whether a system was fit for purpose requires consideration of the interaction between design, materials, fabrication processes, inspection regimes, operating conditions, and long-term service performance.

AHB provides independent technical assessment of structural and pressure retaining systems across a wide range of industrial sectors. This may involve reviewing design documentation, fabrication records, inspection reports, material certification, operating data, maintenance history, and evidence of deterioration or failure. Particular attention is often given to structural steelwork, bridges, tanks, pressure vessels, pipelines, pipework systems, boilers, heat recovery steam generators, and other high-integrity engineering assets.

Where failures or disputes occur, assessment of structural behaviour, pressure boundary integrity, damage progression, and compliance with recognised engineering standards can provide critical evidence. Understanding how these systems perform throughout their lifecycle is often essential when determining the causes of failure, evaluating technical compliance, assessing liability, or establishing whether engineering work has been performed to the required standard.

Because structural and pressure retaining systems frequently involve multiple technical disciplines, including welding engineering, metallurgy, corrosion, non-destructive testing, fabrication practices, and quality assurance systems, their assessment often requires an integrated engineering approach. This expertise supports forensic investigation of failures, independent technical advisory services during project delivery, and the preparation of expert evidence in engineering and construction disputes.
