The dissertation is on the measurement of the strain caused by the characteristics and thetemperature changes of the TIG welded zone which is used with 3D ESPI system that is functionallymodified through the laser ESPI system. Experimental results have derived from the fact that the weldedzone has micro crack during the various phased of the process such as rolling, alkali cleaning, aircooling and heat processing due to the repetitious up-and-down of the temperature. Especially, both 60℃and 90℃ are selected to measure the strain on the welded zone which can be effected by these twotemperatures in the manufacturing process.
The flat plate differences between ESPI and the strain gage are within 2 %, and they are theexactly same with the results from the temperature changes of 60 ℃ and 90 ℃, and also within 3 %and 4 %. As the tensile load increase, the strain of aluminum material increases linearly. Also the sameeffect are observed as the temperature goes up with irregular-line type. The comparison of the strain byESPI and the strain gage in the welded specimen is within the 2.6% when it is under the roomtemperature and low-load conditions, while it is measured within 3 % under the high load condition.
