Thanks to fiber laser technology, it is possible to machine even demanding materials without difficulty, quickly and with high quality. With the FLW-ENSIS and a range of new features, AMADA has further enhanced these properties.
AMADA had already opened up a new dimension in industrial welding when it started using with FLW fiber lasers in its systems. These permitted the trouble-free machining of demanding or highly reflective materials such as copper, brass or titanium, as well as of combinations of materials with different melting points. The FLW-ENSIS now introduces new functions which extend the scope of application of the welding process, while simultaneously makingit more reliable and economic.
Rotating lens (Weaving)
The welding head is equipped with a rotating lens "weaving". This allows the laser beam to circle within a defined radius and makes it possible to reliably bridge larger gap sizes than were possible in the past. This both with and without a welding rod, even within the same part.
The result is that less material is deposited, the heat input is reduced and precisely defined weld edges that require almost no retouching are achieved. Thanks to the use of the weaving technique, it is possible to bridge gaps that are up to 30% wider than is possible using conventional laser welding systems while retaining the same high quality.
Teach Assist System (TAS)
AMADA has also improved the Teach Assist System (TAS). The result: After programming, it is simply necessary to perform a test run in order to correct any discrepancy between robot and seams manually using the TAS. The system takes a photograph of every fixed point and this in turn is used for the automatic comparison and, where necessary, correction of the seam contours of the subsequent parts. This approach can be used for each individual part as well as for components which have previously been defined at any required distance. No corrections are necessary if the parts have been manufactured within a predefined tolerance range and have been clamped precisely. This further development of the TAS cuts throughput times, reduces possible wastage and can help prevent the need to retouch finished parts.
