Fatigue Failure Analysis

Metallurgical Failure Analysis Metallurgical Engineering Welding Engineering Corrosion Engineering Tribology Materials and Processes Inspection, NDT Welding Inspection, CWI Marine Industry Industrial Training Classes: Centrifugal Pumps Welding Inspection Metallurgy for Non Metallurgist Stainless Steel Corrosion Failure Analysis Mechanical Power Transmission Maintenance Welding Lubrication Technology Inspection, NDT Failure Analysis: Shafts Fasteners Gears Bearings Pumps Compressors Vehicles Tanks Structures Pressure vessels Pipelines Motors Food Processing Power and Energy	Metals will fail suddenly even when the loading has never been exceeded the intended design loads. Metallurgical Failure Analysis has expertise in identifying and solving fatigue failures. The image at left shows a stainless steel pin that failed in fatigue caused by the stress-concentrations from the poor quality welding. All sorts of metals and materials will fail because of fatigue when the right factors of: Environment Applied mechanical loading The number of cycles that the loading is applied
