The invention relates to an improved method of welding non-ferrous flexible foils to a metal plate by Friction Stir Welding (FSW), the method comprising the steps of providing a holding device having a horizontal base member (4) attached at two ends one each longitudinal member (5) formed in a shape of inverted 'L' shape, the base member (4) provided on upper surface a second horizontal member (3); clamping a plate (1) and multiple non-ferrous foils (2) in a horizontal direction at identical thickness level with a zero-gap between their joining surface through application of pressure, the assembly (1, 2) having placed on the second horizontal member (3) and the longitudinal members (5); locating a friction stir welding tool (6) with a rotating pin (7) over the plate and foil assembly (1, 2); causing the tool to rotate upon touching the joining surface and allowing plunging of the pin under optimum pressure to enable the pin (7) to progressively reach the full-depth on the upper surface of the joining line imparting a traverse motion making the tool including the welded component (1, 2) along the welding direction to complete the welding; and removing the welding component (1, 2) from the device.
Device for and method of welding together two joining partners by means of friction stir welding, which prevents the joining partners being contaminated by the welding residue
