Materials for potential use in tokamak first wall high current connectors were selected and tested under conditions that might be encountered in tokamak devices. Disk-shaped specimens of promising metal mixtures were subjected to current densities approaching 23 kA/cm2 (150 kA/in2) in 8 ms pulses, closing pressures ranging from .07 to 2.1 MPa (10 to 300 psi), and a vacuum of 1.3 × 10−1 Pa (10−3 Torr). Contact welding occurred at moderate to low pressure and moderate currents. The resulting welds were very weak, failing at 18–31 N (4–7 lb) in shear.
