Failure analysis of welds is the collection, study and analysis of service conditions to assess possible causes of a break-down and the fault of the failure incident.

WJMG assessments have included the most likely cause of weld failures in pipelines, pressure vessels, tanks, transportation vehicles, mass-produced products and general construction defects which generally have large financial implications.

Welding design, procedures, processes and quality are critical in infrastructure items used on a daily basis to help millions of people. Misaligned components, worn-out mechanisms and extended service life must not succumb to unsafe conditions due to budgetary restraints or unrealistic installation schedules.

Failure Analysis Services

Numerous catastrophic failures of metals have been directly linked to weld defects with exponentially higher costs in lost lives, lost income and replacement expenses.Numerous catastrophic failures of metals have been directly linked to weld defects with exponentially higher costs in lost lives, lost income and replacement expenses.

WJMG provides independent expert assessments and opinions that will stand up in court regarding welds and metal failures. WJMG uses a “hands-on approach” to examine and test exemplar welds and subject welds to determine the most likely root cause of a weld failure.

WJMG has decades of experience in liability determination and subrogation matters.

Common Failure Mechanisms

WFrom Oil Rigs to Bridges, WJMG experts specialize in “hands-on” failure analysis of exemplar and subject welds in all types of metals and plastics.elding defects, Inherent metal discontinuities, Machining defects, Low Cycle Fatigue, Brittle Fracture, Low Toughness at Design Temperature, Stress Risers, Corrosion, Stress Corrosion Cracking (SCC), Hydrogen embrittlement, Creep, Stress rupture and other material specific failure modes.

WJMG experts specialize in “hands-on” failure analysis of exemplar and subject welds in all types of metals and plastics. We work in our own ISO certified laboratory or yours. We employ accurate tools and microscopy with published and proprietary procedures.

Proven Litigation Success

WJMG successfully provides expert testimony in local, state and federal courts.
