Notes:
The mechanical properties of various parts of the welding-line material are different,while they play very important role in the welding structures, such as the differences of the meltedpart and the temperature-affected part. In this paper, a non-contacting laser based technique, ISDG(Interference Strain Displacement Gauge) method, is applied to find out these property differenceson very small specimen. The testing is very successful and the whole stress-strain curves in suchsmall scale are obtained on different parts of the welding-line material. The soften phenomena ofthe temperature-affected part is observed by the comparison of the Young’s modulus and yieldstress between the melted part and the temperature-affected part
