Abstract

See full text

A method for welding profiled elements in plastic material, includes the steps of: preparing two profiled elements, arranged with respective zones to be facing one another; making a groove in correspondence to at least one zone, by a removal operation on a peripheral edge of at least one profiled element; heating the zones to be welded; coupling the zones to be welded to one another, pressing the profiled elements one against the other so as to keep the zones to be welded in reciprocal contact. The coupling step includes: melting the zones to be welded into one another in order to define a welding bead; making a containing compartment defined by the groove, the welding bead being made internally of the containing compartment; and arranging a containing presser in correspondence to the containing compartment for preventing exit of the welding bead from the compartment itself.
