In friction stir welding in which members (70,76) to be welded progressively along a welding line (79) are fixed to a support (20) and are friction stir welded by means of a tool (50) rotating on an axis, the axis of the tool is inclined relative to the welding line such that in the direction of welding along the welding line the end portion (51) is advanced with respect to the larger diameter portion (52), and during at least part of the friction stir welding the support (20) is rotated about an axis which is inclined relative to the axis of the rotary tool. The method is especially applicable to welding a continuous path, such as a circle. <IMAGE> |
