Embodiment Construction
[0043] The above objects of the present invention are achieved by adopting aluminum alloy rolled parts and a rotational friction welding method.
[0044] A reinforced frame using aluminum alloy rolled parts for an LCD panel according to the present invention is obtained by rolling four frame parts so as to obtain an L-shaped section, cutting these parts to a suitable length, and then closely connecting these parts to each other into a square shape frame shape. The technical feature is that the corresponding ends of the frame parts are brought into contact, and the four corners are joined by a rotational friction welding method.
[0045]The aluminum alloys used to reinforce the frame according to the invention are wrought aluminum, the most widely acceptable classification of which is as follows: 1000 series are pure aluminum with an aluminum content of at least 99.00 wt %; 2000 series are aluminum copper alloys; 3000 series are aluminum manganese alloys; 4000 series is alumin...
