Friction welding method for a panel structure

A method of manufacturing a composite body having a welded zone at which two members (31,32) are joined by welding; comprising the steps of(i)arranging said members (31,32) edge-to-edge for welding so that said two members at the welded zone have first surfaces and have second surfaces at the opposi...

Zusammenfassung:	A method of manufacturing a composite body having a welded zone at which two members (31,32) are joined by welding; comprising the steps of(i)arranging said members (31,32) edge-to-edge for welding so that said two members at the welded zone have first surfaces and have second surfaces at the opposite side of said members from said first surfaces,(ii)performing a friction stir welding process by inserting a friction stir welding probe (50) into said members at said second surfaces thereof, so as to unite the two members by forming, in said friction stir welding process, a welding bead (45), characterised in that said bead (45) extends through said members from said second surfaces thereof to said first surfaces thereof thereby providing a flush and smooth join of said first surfaces, and in that said first surfaces provide in the welded composite body an exterior face of the body at the welded zone.
