Residual Stress Generation:
During processes such as rolling, forging, extrusion, drawing, bending, and stamping, the material surface layer undergoes significant deformation (plastic deformation), while the core experiences minimal deformation (elastic deformation).
Machining/grinding: Cutting tools or grinding wheels exert intense compression, shear, and friction on the workpiece surface, leading to severe plastic deformation and even microstructural changes in the surface layer.
Shot peening/sandblasting/roller pressing: High-speed projectile impacts or roller compression cause local plastic flow (such as surface layer extension) on the material surface, all of which generate residual stress.
Multifunctional Testing:
Rapid analysis of residual stress in materials such as carbon steel, alloy steel, stainless steel (austenitic, duplex stainless steel, martensitic steel), nickel-based materials (N08810, N08120, N04400, N06600, N06617, etc.), titanium alloys (pure titanium, α-type titanium alloys, α+β-type titanium alloys), aluminum, alumina, copper, copper oxide, zirconium, zirconium alloys, silicon nitride, silicon carbide, etc., in forms including plates, pipes, field welds, and heat-affected zones.
Compliant with international and national standards for the sin²ψ method: ASTM E915-21, EN15305-2008, GB/T 7704-2017, JJF1083-2023, and JB/T9394-2011.
Laser auto-focusing and distance measurement, enabling non-destructive and rapid testing.
Three-axis multi-directional testing capability, with flexible rotation of the measurement unit for multi-angle analysis.
