Method for manufacturing, by capacitor-discharge welding, metal-plate radiator elements for domestic heating systems, and radiator element obtained therewith.

摘要

Method for manufacturing metal plate radiators for domestic heating systems that comprise a plurality of radiator elements, each radiator element being formed by two heads (11a) connected by multiple pipes (12); the heads being formed by respective juxtaposed half-shells and being provided with fittings for connecting the multiple pipes (12). The method is adapted to reduce the manufacturing costs of the radiator elements and to improve their structural qualities, and comprises a first step for connecting the half-shells and for forming each head, and a second step for connecting the pipes (12) to the fittings of the head and for forming the radiator element; both steps are performed by capacitor-discharge welding by means of respective electrodes (30a,30b) that simultaneously act as elements for retaining and mutually positioning the elements to be welded. <IMAGE>
