The evaluated shielding gases were helium (He), argon (Ar) and different mixtures of He and Ar. Weld penetration, tensile strength and formability (Erichsen test) of laser welds were found to be strongly dependent upon the shielding gas types. The ability of shielding gas in removing plasma plume and thus increasing weld penetration is believed to be closely related to ionization potential and atomic weight which determine the period of plasma formation and disappearance. It was found that the higher helium shielding gas flow rate, the deeper weld penetration and the lower weld width.}, language = {en} } @article{WollertLeidinger2010, author = {Wollert, J{\"o}rg and Leidinger, Rafael}, title = {Automation trifft Automotive : SPS in der Fahrzeugtechnik}, series = {Elektronik automotive : Magazin f{\"u}r Entwicklungen in der Kfz-Elektronik und Telematik}, journal = {Elektronik automotive : Magazin f{\"u}r Entwicklungen in der Kfz-Elektronik und Telematik}, number = {4/5}, publisher = {WEKA Fachmedien}, address = {Haar}, issn = {1614-0125}, pages = {44 -- 48}, year = {2010}, abstract = {Eine SPS im Kraftfahrzeug?
