Method for disassembling a reinforcement from a part
A method of disassembling reinforcement from a part, the method including: fastening at least one metal stud on one side wall of the reinforcement and at least one other metal stud on the other side wall of the reinforcement, the studs extending substantially perpendicularly to the side walls on which they are fastened; moving the studs apart from each other to space apart the side walls of reinforcement and disengage snap-fastener mechanisms thereof from complementary mechanisms of the part; and removing the reinforcement from the part.
1. A disassembly method for disassembling a piece of reinforcement from a part,
the reinforcement being releasably fastened on the part and including resilient rims co-operating with grooves of the part,
the method comprising:
fastening at least one metal stud on side wall of the reinforcement and at least one other metal stud on a second side wall of the reinforcement,
the studs extending perpendicularly to the side walls on which the at least one metal stud and the at least one other metal stud are respectively fastened;
moving the studs apart from each other to space apart the side walls of the reinforcement and disengaging the resilient rims from the grooves of the part;
and
removing the reinforcement from the part,
wherein the studs are fastened to the reinforcement by welding,
the studs being used as electrodes for the welding during which at least one electric arc is to be generated between the reinforcement and a first end of each stud to melt the first ends or to melt a filler metal,
thereby forming molten metal serving to fasten the first end of each stud to an outer surface of the side walls of the reinforcement, and
a second end of each stud extending outward from the side walls of the reinforcement.
2. A disassembly method according to claim 1 , wherein the studs are fastened respectively to ends of two branches of a pair of pliers that is used for spacing the studs apart from each other.
3. A disassembly method according to claim 1 , wherein the part is a turbine engine vane or blade, including an airfoil and a piece of reinforcement on at least one edge of the airfoil, each piece of reinforcement covering or forming the edge of the airfoil and extending over an entire longitudinal dimension of the edge of the airfoil, the reinforcement being releasably fastened on the airfoil and including the resilient rims co-operating with the grooves of the airfoil.
4. A disassembly method according to claim 1 , wherein the rims are formed by free edges of the side walls folded inwards and towards a middle of the reinforcement.
