摘要：
A method and apparatus for making a welded thermoplastic polymer article are provided. The method includes the application of a vacuum combined with sufficient heat to make the polymer flowable. The method and apparatus are especially well-suited for welding thermoplastic polymer sheets to the interior of process vessels. The resulting article has improved qualities over articles which are welded by other methods.
