Cross-sectional hardness of aluminum welds (spot welding)
株式会社アイテス
We conducted hardness measurements on aluminum spot welds that were subjected to cross-sectional observation, and we would like to present an example of the trends observed in Vickers hardness, Young's modulus, and elasticity ratio. X-ray radiographic observation confirmed the presence of voids within the weld. Cross-sectional observation revealed that the central void was a blowhole. Furthermore, the results of the hardness measurements indicated that the area near the blowhole was hard but had low stiffness and was prone to deformation, while areas slightly away from the blowhole exhibited higher stiffness and were somewhat brittle.
