A DEVICE FOR MEASUREMENT OF TEMPERATURE DISTRIBUTION IN WELDING

摘要

PURPOSE: An apparatus for measuring the temperature distribution in welding is provided to analyze the temperature distribution and thermal stress of base material in the welding by using a thermocouple. CONSTITUTION: An apparatus for measuring the temperature distribution in welding comprises a base plate(10), a fixing jig, a thermocouple member and a temperature calculating unit. The fixing jig(20) supports each base material so as to be detachable so that a pair of base materials are welded. The thermocouple member(30) is adhered on a surface of the base material at regular intervals. The temperature calculating unit measures the electromotive force of the thermocouple member.
