Abstract

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.
