Encouraging results in copper to steel deep penetration welding with a CO2 laser have been obtained, demostrating yet again that high reflectivity metals can easily be laser processed.
The difference in behaviour between the two metals is discussed as are the advantages deriving from working copper without an oxygen assistance gas flow.
Mechanical tests and metallurgical considerations confirm the applicability of these results to industry.
