Laser welding for every need

Exhibitors show the broad spectrum of technology

Laser welders enable their users to work very quickly and with high quality. These advantages explain why this technology has firmly established itself in the jewellery industry. Baselworld visitors can examine the true advantages of the laser welding process for themselves. A selection of these devices is on display in Hall 4, where, for example, Bijoutil (4.1, D25) will be presenting the DaDo laser welding machine on its stand. The name says it all: ‘Dado’ means ‘cube’ in Italian. This device has a cubic shape and is therefore more compact than conventional machines.

Sisma's LM-D product family“But the really phenomenal aspect is the price,” says Francis 
Schaeffert, Head of Back Office at Bijoutil. In the past, anyone who wanted to work with laser welding technology had to be prepared to pay a little more than for alternative methods. DaDo, on the other hand, can be purchased for less than 5,000 Swiss francs. “This puts us in the same price range as electric welding equipment,” says Schaeffert, who adds that Dado is also very easy to operate. The machine can be operated either manually or via an app on a tablet or smartphone. Simply unpack it, set it up, fill it with coolant liquid, download the app – and the laser welder is ready for use.

DaDo users can weld spots with 𠊍iameters ranging from 0.2 to 1.5 millimetres. The operator’s mobile devices display additional information about the laser welding process. “We designed DaDo in response to the needs of many customers who want to use economical and space-saving equipment,” Schaeffert explains.

Laser welding is also the focus of 
J. Schmalz’s presence at the show. This company will also be exhibiting DaDo on its stand (4.1, F13). �vices from Coherent and Sisma will be on display there too. For example, visitors can view the LM-D product family, which uses Smart Spot technology. Developed to ensure a reproducible welding process, Smart Spot enables its users to simplify and thus shorten the time required for even the most complex working cycles. The manufacturer points out that the highly efficient dedicated filter ensures complete recovery of precious material. In addition, the devices offer a new ergonomic design and low operating noise.

Another technical highlight is an Eco mode, which switches off unused system components during idle times. The devices also offer USB and Ethernet connectivity, a barcode reader and full digital electronic control for accurate diagnostics, higher pulse stability and longer lamp life. One device from this series, which will also be on display at J. Schmalz’s stand, is the LM-D Ready. It offers easier access to the working area, which enables its operator to work even more quickly and intuitively.
