Mockups of blanket cooling plates manufactured in different diffusion welding setups

The high amount of energy applied to the structural elements of a future fusion power plant results in the need of using plates with meandering cooling channels. Of the different proposals [J.-F.

Mater., 386–388 (2009) 922. [1]]. made to manufacture such plates, a diffusion welding process of two symmetric halves is a promising candidate. This paper will focus on the recent industrial manufacturing series conducted to increase the dimensions of the workpiece. In this case, the diffusion welding process was performed in a hot isostatic pressing setup. In a former attempt, a uniaxial diffusion welding setup had been applied.
