Q&A

Here we introduce some of your frequently asked questions on friction welding.

Q&A

  • What kind of metal can friction welding be used for bonding?

    The bonding of different metals is known as dissimilar metal bonding, but friction welding can be used for most metal materials whose main component is iron. However, friction welding can also be used for the bonding of difficult combinations of certain nonferrous metals such titanium and molybdenum.
    For details, please refer to the “Table of Possible Combination of Materials for Friction Welding”, or consult us from the “Trial production / demonstration” menu.

  • Is it only possible to bond metals? Can you please tell us about any other examples?

    Friction welding can also be used for plastic bonding, and we have some examples available. One of the characteristics of plastic bonding is a beautiful finish with no bubbles on the bonding surface. Wood bonding is not possible.

  • When we hear the term friction welding, we think of the automobile industry, but is it difficult to apply friction welding to other fields?

    Friction welding technology is a metal bonding technology that can be applied to a wide range of applications in different fields from aircraft, civil engineering and construction, machine tools, and sports goods such as golf clubs, to other machine parts and space development. It is not a specialized technology for the automobile field.
    Since research first began in 1956 in the former USSR, Toyoda Automatic Loom Works, Ltd. (currently TOYOTA INDUSTRIES CORPORATION) successfully applied the technology as mass-production equipment for the first time in Japan in 1962. Izumi has contributed to the popularization of this technology for half a century up to the present day, and its application in the automobile industry may have come to the fore.
    Please refer to the “History of Friction Welding” or “Friction Welding Examples” for details.

  • Integrated machining is not possible, and so we are considering friction welding. The part in question is subject to constant vibration, and we are worried out fatigue strength and bonding strength of the welding surface.

    The fatigue strength of the friction welded material rises a little after friction welding, and once finished, becomes as strong as the base material by then normalizing. Furthermore, the hardness near the friction welded part rises in the case of material with good hardenability. By performing normalizing, the hardness will be the same as that of the material.
    In the case of dissimilar metals, consider the intermediate strength between both metals.
    Refer to “Quality of friction welding” for details.

  • We are giving serious consideration to adopting friction welding in particular. What kind of instructions should the drawings we prepare contain?

    Please provide us with drawings of the applicable workpiece, as well as information on the material used. Izumi will come up with a suitable proposal based on this information.

  • We want to gather data to verify quality, yield ratio, and productivity under the same conditions as our workplace, but is this possible?

    At Izumi Machine Manufacturing Co., Ltd., we offer trial production and evaluation, as well as samples to allow customers to gather data on research and development, manufacturing process improvements, and mass-production studies, as well as to help make decisions on machine adoption.
    Please refer to the “Trial production / demonstration” menu for details.

  • We are considering adopting Izumi machines for the lines we are currently running. We have constraint conditions for our existing processes, but can you deal with this?

    With most of our customers, our friction welding machines are not adopted as is, but are used with some form of modification. Izumi also carries out production line design and manufacture, and so we are able to offer a total friction welding solution, including improvements to the previous and next processes. Please don’t hesitate to contact us from the inquiries menu.

  • We are considering adopting Izumi equipment for our overseas manufacturing bases. What procedure is necessary?

    To ensure that customers in the process of rapidly expanding their overseas footprint are able to use our equipment with peace of mind, Izumi provides support through a reliable service organization with the help of our overseas partners. Please refer to the “Overseas Partners” menu for details, and don’t hesitate to contact us if you have any further questions.
