Abstract

In a method of producing a fuel tank from plastic, a heating element is located between two shell parts to be welded to one another. When the shell parts are pressed together, the heating element melts into the plastic and produces a weld that provides a fuel-resistant seal. The fuel tank subsequently has a particularly exact shape.
