Abstract
The present invention provides a method and an apparatus for induction welding a first plastic member to a second plastic member. A contacting portion of the first plastic member is clamped into contact with a contacting portion of the second plastic member. A current is induced in conductive material external to the plastic members and proximate one of the contacting portions to generate heat sufficient to bond the contacting portions together. The method and apparatus are capable of sealing plastic members that are devoid of conductive material.
