How to Detect the Quality of Forged Shafts

Forged Shaft Quality Inspection Methods:

Appearance and Dimension Inspection: Use a coordinate measuring machine (CMM) or a dedicated torsional deformation testing instrument to check for surface defects and dimensional accuracy, ensuring parameters such as ovality and concentricity meet design requirements.

Internal Defect Detection: Employ ultrasonic flaw detection (single straight probe radial detection) to identify internal cracks, shrinkage cavities, and other defects, supplemented by angle probe circumferential detection when necessary.

Material and Performance Verification: Evaluate material properties through chemical composition analysis, hardness testing, and tensile testing to ensure the shaft meets requirements for strength, toughness, and other characteristics.
