Subproject B06 – Collaborative Research Center 1368: Oxygen-free production

Subproject B06 Arc welding of copper

Pure copper has a high electrical and thermal conductivity, which depends on the oxygen-free nature of the material. Since copper has a high affinity for oxygen, thermal joining processes are therefore to be regarded as critical. Even under shielding gas, contamination cannot be prevented. In subproject B06, arc welding of high-purity copper in an XHV-adequate oxygen-free process atmosphere is to be developed. A comprehensive model starting at the temperature development in the plasma and the corresponding dissolution of existing process gases, to the final component purity will be developed.
