Test equipment monitoring
Regular calibration and verification of testing machines and hardness testers ensure accurate and traceable measurement results. This is crucial for quality assurance.
Physical-Chemical Mechanism of Action
Calibration of testing machines ensures they deliver correct readings. This involves adjusting the machine to known standard values or reference objects. Verification ensures the machine still meets these standards.
Metallurgical Relevance & Welding Risks
Incorrect readings can lead to errors in hardness determination, which can point to inaccurate welding parameters or wrong material selection. This can cause cracks, failures, or insufficient component life.
Shop Practice & Action Guidelines
Calibrate testing machines at least once a week and check them daily. Use reference objects with known hardness values for calibration. Document all calibrations and checks thoroughly for traceability.
