摘要

A thermoplastics storage battery casing is joined to its cover plate by welding. A heating plate is placed between the cover plate and the casing and edges of both components are plasticised by heat. The join is made after the heater is withdrawn by applying pressure. The process is automated and a hydraulically operated press is incorporated.
