Weld Analysis and Inspection Service
At Lucideon, our weld analysis service offers comprehensive inspection, testing, and failure analysis for welds across a range of industries that rely on metal joining for safety, durability, and performance.
Our expertise ensures that welds meet exacting physical and chemical specifications, minimizing the risk of structural failure and promoting the highest safety standards.
Weld analysis is a vital component of quality assurance in welding processes, aimed at ensuring that welded joints meet mechanical, metallurgical, and safety standards required for specific applications. It involves the examination of weld properties, such as tensile strength, microstructure, porosity, and chemical composition, to identify flaws that could potentially lead to joint failure.
Metallography, chemical, and physical testing are commonly used in the industry to detect internal defects, assess the heat-affected zone, and evaluate a weld’s integrity. By providing insights into potential problems like cracking, inclusions, or phase transformations, weld analysis supports the optimization of welding parameters, improves the longevity of components, and reduces the risk of costly failures.
It is an essential practice in industries ranging from aerospace and automotive to infrastructure, where the reliability of welded components is critical.
Why choose weld analysis?
The primary purpose of weld analysis is safety. By rigorously testing welds, we help reduce the likelihood of failure in applications where a compromised weld could have severe consequences.
Our analyses can identify whether welds meet specifications for depth of penetration, hardness profiles, and other critical parameters.
In addition, we conduct failure analysis to determine the root cause of issues in failed welds, identifying problems and helping to prevent future occurrences.
Types of welds analyzed
We assess a variety of weld types, including:
- Electrode welds
- Electron beam welds
- Laser welds
- Spot welds
Each weld type has unique characteristics and potential issues, and our experienced team understands the specific requirements and challenges associated with each.
Failure analysis
For failed welds, we provide detailed failure analysis, identifying root causes such as microstructural changes, cracking, and inclusions within the heat affected zone (HAZ). This analysis can be critical for safety improvements and quality control, helping you understand where and why failures occurred.
Industry experience and expertise
Our weld analysis experts, based in our US laboratories in Schenectady and Greenville, bring decades of experience in testing primarily steel and super alloy nickel components. While our focus is on these materials, we also handle aluminum, copper, and other metals. With a commitment to quality and safety, Lucideon's weld analysis service is trusted across industries where weld reliability is critical. Our experienced team, advanced methodologies, and ability to provide both qualitative and quantitative data make us a reliable partner for all your weld testing needs.
Comprehensive testing & analysis
Our weld analysis includes testing on both test coupons and in-situ welds - whether they are new or have failed. Our services cover:
- Specification compliance: verification against defined size, porosity, and defect specifications
- Physical inspection: we examine cross-sections, depth of penetration, and identify potential defects such as lack of fusion, cracking, and inclusions
- Hardness profile: analysis across welds and the heat-affected zone (HAZ), identifying any softening or structural changes
- Elemental diffusion analysis: using microprobe and EDS mapping, we track element migration within the weld and surrounding areas, ensuring the weld's chemical integrity
- Defect identification: detection of underfill, overfill, undercut, and surface issues like splatter that can compromise functionality and appearance
- Onsite evaluations: supporting audit processes by verifying operator skills and compliance with welding standards
