Method for corrosion protection of e.g. hollow frame unit of car, involves placing fusible solid products e.g. wax, in hollow body, melting products, and allowing products to cool to freeze corrosion product in gap

摘要

The method involves placing fusible solid products (10, 11) e.g. wax, in a hollow body during hooking structural elements e.g. hollow frame units, constituting a part of a body of a vehicle i.e. car. The solid products are melted during passage of the vehicle body in a furnace for cataphoresis such that the solid products are provided in a set of gaps (e1, e2). The melted solid products are allowed to cool to freeze corrosion product in the gap after the products are removed from cataphoresis.
