Temperature distribution inside material during the process and the joining strength in friction stir spot welding of PVC by Yohei KURABE, Yukio MIYASHITA, Hisashi HORI

“…It was considered that the size of area friction stirred would be predicted based on the temperature distribution, because size of area with temperature above grass transition temperature of PVC almost coincided with size of area friction stirred. …”
