METHOD AND DEVICE FOR FRICTION STIR WELDING |
摘要 |
<p>[PROBLEMS] A method and a device for friction sir welding capable of achieving sufficient welding strength of a product. [MEANS FOR SOLVING PROBLEMS] Thermal expansion of each tool (2, 3) is prevented because each tool (2, 3) is cooled by air jetted from each air nozzle (4, 5), and this appropriately maintains a gap between an upper tool (2) and a lower tool (3). As a result, a friction stir-welded portion having a residual base plate thickness with an appropriate thickness between an outer panel (6a) and an inner panel (6b) is formed, achieving sufficient welding strength of an engine hood. Air cooled by an extreme low temperature air producer (16) is jetted from each air nozzle (4, 5) to cool each tool (2, 3), and each tool (2, 3) is effectively cooled. The structure above enables thermal expansion of each tool (2, 3) to be constrained to a minimum level to produce a friction stir-welded portion with a residual base plate thickness having a more stable thickness, and as a result, welding strength of the engine hood is sufficiently achieved.</p> |
