Mechanical testing also refers to mechanical performance testing. It mainly tests the mechanical properties of metals, and tests the properties of conventional metals such as stretching, bending, yielding, flattening, and hardness.
1. The tensile (yield strength, tensile strength), bending, impact, hardness and other toughness and plastic properties of metal raw materials, and the tensile (yield strength, tensile strength) and bending properties of steel bars.
2. Welding procedure qualification of metal welded parts.
3. Mechanical testing of high-strength bolts
Fastener testing
Testing of the torque coefficient of the bolt connection pair, tightening axial force, tension (yield strength, tensile strength), hardness and other properties, and the anti-slip coefficient of the bolt connection plate. Method
