Conversion Procedure
Conversion procedure is a method for converting hardness values between different scales (e.g., Vickers to Rockwell). It's based on empirical curves and is material-dependent.
Physical-Chemical Working Mechanism
Conversion methods use empirical data that describes the relationship between hardness values on different scales. This data is obtained from measurements on reference samples and is presented in the form of characteristic curves.
Metallurgical Relevance & Welding Risks
Using a conversion method can lead to errors if the chosen method is not suitable for the specific material. This can result in the actual hardness of the weld being underestimated or overestimated, which poses risks related to mechanical strength and behavior under load.
Workshop Practice & Action Instructions
Always use the correct conversion method for the specific material. Make sure the characteristic curves you use apply to the exact filler metals and the chemical composition of the base material. If in doubt, consult the manufacturer's information or talk to a metallurgist.
