The hybrid welding technology has been developed by LPKF Laser & Electronics AG, Plastics Welding Division in cooperation with the Institute Bayerisches Laserzentrum gGmbH. It is an approach to provide cost-effective and tool-independent laser welding systems, which are able to compensate for the geometrical deviations that large, three-dimensional joining partners are afflicted with.
The technology employs a combination of laser light with the infrared radiation emitted by conventional halogen heating lamps. This concept of a dual irradiance has already proven to increase both, processing speed and fault-tolerance.
Target applications of the hybrid welding technology are not only structural automotive parts, e.g. head and rear lamps and plastic engine parts, but also consumer products and medical applications.
Our specialists are available to discuss all details with you.
The specialized TwinWeld3D is designed to handle large, free-form components. The laser delivery head, halogen lamp and clamping arm are attached to the end of a 6-axis robot, allowing for flexible delivery of the laser beam at any point along large parts.
