Abstract
Disclosed is a reinforcement frame for a display panel using aluminum alloy extrusion members and an apparatus and a method for manufacturing the same, wherein, while a number of unitary aluminum alloy extrusion members abut one another, a welding head is used to cause the abutting portions to undergo friction resulting from high-speed rotation so that the members are melted and welded to one another by the resulting frictional heat.
