| 概要 |
The simulation of resistance spot welding (RSW) is used to approximate the experiment results and can be used to predict the nugget weld size. This article presents the 2D-Axisymmetric thermal-electri...c coupled model with properties of Electric Contact Resistance (ECR). The objective of his study is to investigate the effect of ECR thickness and the ECR's initial value on weld nugget geometry and thermal history. Direct current (DC) was applied with 10kA. Measurement of nugget geometry was performed by observing the temperature from the center of the weld through vertical and horizontal distribution. The result showed that the thickness of ECR and the ECR initial value significantly influenced the nugget temperature formation result.続きを見る
