| Complete solution for wire-guided joining processes | |
Fully integrated monitoring of brazed/welded seam qualityPrecitec is now offering a new complete solution for wire-guided joining processes. The "Scansonic ALO3" is a brazing/welding head with a fully integrated coaxial quality monitoring system. The system requires no additional space and gives users the cutting edge performance of Precitec products. Seam geometry monitoring detects the profile and the position of the fillet welds on the lap joint and double-flanged seams on the butt joint. Fixture mechanisms can be optimally matched to the welding results, irrespective of any additional quality monitoring components. The welding head causes no obstruction whatsoever in the processing area and can easily travel in and out between the fixture mechanisms. Profile measurement takes place a few millimetres behind the welding spot, necessitating only a minimal overrun at the seam end. Frequent weld defects like lack of fusion, wire on the upper/lower metal surface, gaps between the metal sheets, etc., can now be reliably identified and monitored. The system also recognises open pores from 0.5 mm upwards. Existing systems can easily be retrofitted. |
| Precitec hosts laser welding workshop in the USA | |
|
Precitec USA hosted a 2-day laser welding workshop in March this year. The programme consisted of presentations and demonstrations in the three main topics - laser hybrid welding, welding with the LWM quality monitoring system and laser beam welding with the WobbleTracker. Lectures on these topics were also given by other companies. Since this event was very well received by customers - and we had interesting and promising discussions with potential customers, we have decided to host more workshops in the future. Around 50 well-known companies and decision makers responded to our invitation to attend the event, which took place on the IPG premises. |
| Welding & Cutting Fair, India | |
|
From 10-12 February, Precitec presented its products for laser cutting and welding at the Welding & Cutting Exhibition in Mumbai, India. The Exhibition proved to be very popular and we had many discussions with potential customers. A great deal of interest was shown in our CO2 laser cutting products. Our presence at the Exhibition on the German joint stand was supported by our Indian representatives and our contact on site, Laser Science Services(I) Pvt. Ltd. |

Measure Surfaces and Layer Thicknesses Even More Economically with the New Optical Sensor CHRocodile S As well-performing as it is economical, we present you with the newest generation of distance, topography and thickness measurement systems from Precitec Optronik. With the CHRocodile S, our company expands its well-established series of opto-electronic sensors in the market. This new, non-contact measurement system offers surface measurements with a precision of 30 nm and a resolution of 3 nm all at an unprecedented economical value. And the new sensor will also impress you with its unique performance features. Surfaces with rapidly changing reflective properties will be reliably measured at the high rate of 2,000 measurements/ second, without adjustment, interrupted production or additional calibration. And it doesn't matter whether you're dealing with highly reflective, polished, matte-black or transparent materials. CHRocodile S is an ideal solution for invariable or variable applications, inline or offline. The high aperture of our optical probes further enhances the level of quality generated by the sensor's automatic brightness adjustment. A long-life diode serves as the light source for measurement in the new system. This, together with the conscious decision to avoid using moving parts in the electronics and sensing heads, makes CHRocodile S practically maintenance free. We were even able to do without a cooling fan, as used in classical constructions. This allows the measurement system to show its strengths both in the clean room and in the raw production environment. CHRocodile S can process both trigger and encoder signals. Synchronization with external devices or integration into the process controls of a production facility is easily achieved using high-performance interfaces (RS232, RS 422, USB, analog). With its highly compact housing, the device can be used on a table-top, easily integrated into machines or very easily mounted in control cabinets. CHRocodile S offers significant advantages for users in industry and research
All in all, an idea that adds up:

| New YW52 with integrated WobbleTracker | |
|
He welds seams that are exactly positioned and only as wide as necessary! Welding variable joint positions is a challenge which not every welding head can master. The tools of choice here are intelligent welding heads. They measure the position of the joint in order to place the weld seam at the correct position. Every welding task also requires a spot size that is adapted to the application - and the effective width of the laser beam can be flexibly optimised from one seam to another, ensuring a stable process. The weld seam width is thus only as wide as necessary, enabling the highest possible welding speeds. On the fair SCHWEISSEN & SCHNEIDEN Precitec shows for the first time the YW52 high power Welding Head with integrated WobbleTracker. All his functions are fully integrated into the new YW52 welding head, without the need for additional external sensors, cameras or external linear positioning. |
