Answering “Why” to Prevent Recurrence

When a critical material, component, or structure fails, immediate repairs are only a short-term solution. The key to long-term reliability lies in understanding why it failed. Failure Analysis investigates the physical cause—such as fatigue, corrosion, or overload—while Root Cause Investigation uncovers the deeper systemic or procedural issues that led to the failure.

BQCIS provides multidisciplinary failure investigations led by materials scientists, welding engineers, and process specialists. We apply advanced analytical and field techniques to reconstruct failure events and identify the true root cause.

Our reports deliver clear, evidence-based conclusions along with corrective and preventive recommendations—ensuring the issue is not only resolved but eliminated from future operations.

Key Investigation Activities

Physical Failure Analysis (Laboratory-Based)

Using techniques such as scanning electron microscopy (SEM), metallography, chemical analysis, and hardness testing, BQCIS identifies the physical failure mode—whether fatigue, brittle fracture, or stress corrosion cracking. This forms the technical foundation of every investigation.

Root Cause Investigation & Data Review

Our structured approach (5-Why, Fishbone, or Fault Tree Analysis) examines design, operation, maintenance, and human factors. We correlate laboratory findings with procedural data to identify not only the failure’s physical cause but the organizational root cause behind it.

Success Story

Failure Analysis of Welded Joint Prevents Structural Collapse

The Challenge:

A structural steel truss in a logistics facility failed at a weld joint during commissioning. The client required immediate root cause analysis to assess safety implications and liability exposure.

Our Solution:

BQCIS collected the failed section and performed detailed metallographic and SEM fracture analysis. Findings revealed hydrogen-induced cracking due to moisture-contaminated consumables and inadequate preheating.

The Result:

The investigation enabled rapid procedural correction and inspection of identical joints across the site, preventing further failure. The client also implemented a new consumable control system and revised WPS to ensure permanent corrective action.
