Root Cause / Damage Analysis

Damage; is the failure of a structure or structure element to perform the functions expected of it. Damage to a product can result from any of the material selection, design, manufacturing, shipping, assembly, and use phases, and determining the root cause of the damage can be challenging for manufacturers and operators. Lack of root cause analysis after come across to damage makes it difficult to prevent similar product damage that may occur in the future, and hinders manufacturers and operator

Common causes of damage are listed in the table below.

REASON FOR DAMAGE	RATE (%)
Wrong material selection	38
Manufacturing errors	15
Heat treatment errors	15
Design errors	11
Unsuitable conditions of use	8
Environment conditions	6
Lack of quality control	5
Mixing of materials	2

What is Damage Analysis?

Damage analysis is a comprehensive examination to determine the mechanism of damage and the root cause of the damage. Differences between the undamaged state of the product and the damaged state are revealed, and remedial solutions are being developed. Root cause analysis involves collecting and analyzing data and taking remedial and / or preventive measures. To accurately determine the root cause of the damage, an experienced damage analyst is required that can identify signs of damage, analyze observations, and achieve correct results using its logic.

İmplementation Method

Selection of samples
Collection of information about the history of samples (manufacturing method, heat treatment, conditions of use, etc.)
Collection of information about the damage
First evaluation meeting (selection of analysis methods to be used)
Visual inspection of samples
Determination of the chemical composition of the samples
Determination of the mechanical properties of samples
Mechanical and metallurgical investigation of samples
Second evaluation meeting (evaluation of analysis data)
Detection and reporting of damage mechanism and root cause
