Abstract
A method and apparatus for welding a header to a heat sensitive cap to form an electro-optic device housing without weld flanges. A collet electrode is used to provide a radially compressive force which provides good electric and thermal contact to the wall of the heat sensitive cap and maintains the glass to metal seal under compression.
