Abstract
An electrically actuated igniter squib is formed by welding a cup containing a pyrotechnic material to a header inserted in the cup, thus forming a hermetic seal. The diameter of the header exceeds the diameter of the cup and the two are joined by forcing, under pressure, the header into the cup to achieve a tight readily welded joint.
