Abstract

A method and apparatus for welding two or more subcomponents together is described. The subcomponents may be welded to one another along seams, whereby sections of the seam that comprise similar materials are heated to a degree suitable for joining together those particular portions of the seam. Other sections of the seam may be heated to a different degree depending upon the material characteristics employed in that section of the seam. Embodiments of the apparatus include features for holding the subcomponents, simultaneously heating seams of each component, positioning the mating subcomponents together, and applying pressure between mating subcomponents to join them together.
