Conductivity measurement
Conductivity measurement: Determines the electrical conductivity of a material using eddy current methods to check heat treatment states or material mix-ups.
Physical-Chemical Mechanism of Action
Conductivity measurement measures the electrical conductivity of a material using the eddy current method. This process generates a magnetic field that excites the electrons in the material and makes their movement measurable.
Metallurgical Relevance & Welding Risks
The conductivity of a material can vary greatly after heat treatment or in case of material mix-ups. Too high or too low conductivity can indicate incomplete heat treatments, faulty welding processes, or wrong material selection. This can lead to cracks, destruction of mechanical properties, and reduced component life.
Workshop Practice & Action Instructions
To measure conductivity, use an eddy current device. Make sure the material is dry and free of corrosion or contaminants. The measurement should be done at room temperature. If results are unusual, check the heat treatment of the material and check for possible material mix-ups.
