Our investigations deal with vacuum tight laser welds of welding pairs
: soft magnetic iron Vacofer S2 protected with nickel, galvanic plate
d to a thickness of 4 mum, and gold, galvanic plated to a thickness of
0.2 mum-CuNi30Fe alloy thickness of 0.25 mm ; its geometry, microstru
cture and tightness. The thermal expansion influence on compression gl
ass-to-metal seals during the process of laser welding has been estima
ted too.
