Definitions

  • the present invention relates to a friction stir welding method and apparatus used to join multiple workpieces, for example for joining workpieces such as cables in an end-to-end fashion.
  • Friction stir welding is a method in which a probe of material harder than the workpiece material is caused to enter the joint region and opposed portions of the workpieces on either side of the joint region while causing relative cyclic movement (for example rotational or reciprocal) between the probe and the workpieces whereby frictional heat is generated to cause the opposed portions to take up a plasticised condition; optionally causing relative movement between the workpieces and the probe in the direction of the joint region; removing the probe; and allowing the plasticised portions to consolidate and join the workpieces together.
  • Examples of friction stir welding are described in EP0615480 and W095/26254. The benefits of friction stir welding have been widely reported in the prior art, especially in comparison to conventional fusion welding techniques.
  • Friction stir welding is commonly executed using a simple cylindrical or slightly tapered probe or "pin" protruding from a larger diameter flat, domed or tapered shoulder, although in some instances a 'shoulderless' tool has been used comprising of a probe with no appreciable shoulder feature.
  • Typical examples of the common pin tool are described in GB2306366. Many modifications of the simple pin tool are known in the prior-art.
  • Typical workpiece materials commonly joined using friction stir welding are of a relatively low melting temperature and are in this context generally termed as being low temperature metals or materials, that is materials with a melting temperature below 1 100 degrees centigrade. The most commonly friction stir weldable of these materials are metals based upon aluminium, magnesium, copper, lead and other similar materials. It is also possible to join high temperature metals based upon iron, titanium, nickel and others, but often more traditional joining methods using melting/fusion are preferred due to cost issues, particularly in relation to the tool materials required.
  • JP2003-071576 describes a method of joining metal wires or foils, whereby their ends are buried in a terminal plate in a side-by-side fashion and a friction stir weld tool is traversed across each wire through the plate to join the wires and plate together. It is not possible to join workpieces end to end in any fashion using this method.
  • JP2003-126972 describes a method of joining metal wires, plates or foils arranged in parallel (e.g. side-by-side or stacked) using a friction stir welding tool, either with or without a covering plate, whereby the tool is traversed through or across the workpieces. It is not possible to join workpieces end to end in any fashion using this method.
  • JP2004-160477 discloses a method of friction stir welding (typically square section) aluminium sleeves to (typically circular section) aluminium wires.
  • a joined assembly can potential be combined with another, again using friction stir, either side-by-side or end-to-end.
  • end-to-end joining of wires it will inevitably leave a relatively large local increase in cross-section in the form of the sleeve which, especially when scaling up in thickness, may prove excessive and need considerably machining if reduction to original cross-section is required.
  • WO2005/082567 discloses a method of joining (insulation coated) wires by aligning their ends side-by-side, clamping and shaping/crimping them in a die and inserting a friction stir welding tool from the end to join the ends together. This allows joining of the ends without stripping the insulation, but it is not possible to join workpieces end to end in this fashion.
  • JP2014-057994 describes a method of joining (metal coated) wires by aligning portions of their length side-by-side and creating an elongate joint by traversing a tool for a distance along the butted lengths. Although this no doubt creates a joint, it is not convenient nor often feasible to align lengths of workpieces in this manner, or bend them to shape. It is not possible to join workpieces end to end in any fashion using this method.
  • EP1046453A2 describes a friction agitation joining apparatus for joining a plurality of abutted members which includes rotatable chucking portions for chucking opposite ends of the abutted members. This apparatus is suitable for joining abutted pipes, but it is not possible to join other types of workpieces end to end in any fashion using this apparatus.
  • JPH10180467A describes a similar friction agitation joining apparatus to EP1046453A2.
  • the apparatus is suitable for joining pipes together and includes support rollers, but it is not possible to join other types of workpieces end to end in any fashion using this apparatus.
  • JPH10166165A describes a method and device for friction welding capable of dealing with long and large joining faces, as well as vertical, horizontal, or inclined joining faces. However, it is not possible to join workpieces end to end in any fashion using either the method or the device described.
  • WO2015/045490A1 describes a friction stirring tool, a friction stir welding device, and a friction stir welding method with which the parts of the metal materials that are to be welded can be friction stir welded in a suitable manner, while limiting the load applied to the tool, even if the thickness of the parts to be welded varies.
  • the above inventive method is particularly useful for joining workpieces which are not conducive to the more traditional clamping methods used in existing friction stir processes.
  • the inventive method enables the end-to-end joining of cables, where the cable strands cannot be entirely stirred together and do not provide enough material to form a satisfactory joint using existing friction stir processes.
  • the insert or joining body used in methods according to the invention provides the necessary extra material.
  • the cyclic motion of the probe may comprise rotation of the probe, reciprocal motion of the probe, or both.
  • the probe has an accompanying shoulder, where the probe extends from the shoulder. The shoulder can be used to confine displacement of the stirred material, forcibly displace material and optionally provide heating by rotation.
  • the probe and the shoulder are able to move relative to one another, although it is possible to provide a tool in which the probe and the shoulder form a single element.
  • the use of a probe and shoulder which move relative to one another, typically along an axis parallel to the axis along which the probe extends from the shoulder, known in the art as 'retractable pin', provides a method of controlling the placement of stirred material to form a properly consolidated joint, whereby when the probe retracts into the shoulder at least some of the displaced material moves into the area voided by the probe. It is often the case that the joint produced protrudes outside the axis of the original workpiece to leave a thick or bulbous section.
  • the probe and the shoulder of the tool are able to move relative to one another and removing the probe comprises causing the probe to retract into the shoulder whilst at least some of the displaced material moves into the area voided by the probe and further comprises using the shoulder to force further displaced material into the area voided by the probe.

  • the joining body could be made of a combination of materials in itself, or multiple pieces which could be temporarily attached to the ends of the workpieces.

This technique is not as sensitive to the factors detailed above which affect the amount of expelled material, but requires more complex equipment.
