The machine (1) comprises at least one main welding device (3) of a first profiled element (4) and a second profiled element (5) which extend along their respective longitudinal directions and are each provided with at least one extremal area to be welded (6), the main welding device (3) comprising: main retaining means (18, 19) of the profiled elements (4, 5); main heating means (20) adapted to heat the extremal areas to be welded (6); main displacement means (21) of the main retaining means (18, 19) adapted to displace the profiled elements (4, 5) between a mutual spacing away position and a mutual approaching position;
wherein the main heating means (20) comprise two heating plates (27), each of which can be placed in contact with a respective extremal area to be welded (6) and arranged substantially parallel to each other at a predefined distance to define a free volume (V) positioned between them.

A device for welding profiled elements in plastic material includes: a base frame supporting retaining members of respective profiled elements, to engage the profiled elements with corresponding zones to be welded facing one another; a heater for heating the weld zones of the profiled elements; a unit to move the retaining members, to shift the profiled elements between a first reciprocal away direction and a second reciprocal closer direction wherein the zones to be welded are coupled together; and a removal unit utilizing milling The removal unit includes: a supporting frame positioned in correspondence to the retaining members; at least one machining tool; a motor part associated with the tool; and a movement member of the tool, to move it between a first idle condition and a second working condition wherein it is placed between the profiled elements.

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.

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