惯性摩擦焊测温研究

Study of thermometry for inertia friction welding

热电偶测温是现代测温技术中的主要测温方法,但由于热电偶的滞后性,测温的准确度难以提高在。基于惯性摩擦焊接动态测温试验基础上,提出了一种根据热电偶测温原理校正热电偶测温动态误差。通过红外仪测温对校正结果进行了检验,结果较理想,对提高测温准确度具有一定的意义。

Thermocouple instrument is an important thermometry instrument during the modem thermometry practice, but because the proper hysteretic properties of thermocouple ,the accuracy of thermometry can＇ t be improved. The article introduces a correction way based on the thermocouple thermometry principle during the practice of inertia friction welding, and the corrected result also has been checked by the infrared instrument. It has a significance to improve the accuracy of thermometry.
