Failure Analysis

A failure investigation begins with the examination and evaluation of a failed component. Using techniques such as visual inspection, metallography, liquid penetrant/magnetic particle inspection, scanning electron microscopy (SEM), hardness testing, and chemical analysis we determine the root cause of a component failure.

Using the results of such an analysis in combination with the component service history, we make recommendations to our clients and assist them in preparing a corrective or preventative action plan that will prevent a costly or dangerous recurrence. This could involve a change in material specification, a redesign or modification of the component, or an adjustment of the operating parameters.

Wayland Engineering has been performing failure analysis investigations for 25 years. Clients have found particular value in failure analysis when:

• New components and parts arrive with manufacturing defects

Investigation can determine how the defect was introduced, whether it is a systemic issue, and the risks associated with repair or introduction to service.

• Fabricated components are found defective prior to entering service

Investigation can determine if the defects were caused by the fabrication / installation process or if the original subcomponent was defective.

• Unexpected damage is found on in-service components (cracking, corrosion, etc.). Investigation can determine why the damage has happened and when it is occurring. This can help the operator prevent more damage and increase reliability.

Failure analysis can be performed on components shipped to our testing facility in Halifax, Nova Scotia or can be performed onsite using field metallographic replication techniques.
