A methodology for finding unknown or unavailable parts of temperature-dependent material characteristics is presented. Knowledge of these parts is of great importance for solving problems connected with processing of metals at high temperatures where phase changes take place, such as welding or cladding. The paper presents a technique of calibration of these characteristics based on evaluation of experimentally obtained heat-affected zones and allows discovering not only the basic features of the characteristics, but also eventual breaks and other anomalies. The results obtained are illustrated with two examples taking into account the keyhole effects: laser welding and laser cladding. The functionality and efficiency of particular algorithms is also evaluated.

介绍了一种用于查找与温度相关的材料特性的未知或不可用部分的方法。了解这些零件对于解决与在发生相变的高温下加工金属（例如焊接或熔覆）相关的问题非常重要。本文提出了一种基于对实验获得的热影响区的评估来校准这些特征的技术，不仅可以发现特征的基本特征，还可以发现最终的断裂和其他异常情况。通过考虑小孔效应的两个例子来说明获得的结果：激光焊接和激光熔覆。还评估了特定算法的功能和效率。
