New Product from GSI - JK Scanning Systems for JK125 & JK300 Lasers

GSI Group, Laser Division today announced its new scan head control system and software for the JK125 and JK300. This system enables greater control and flexibility as well as reduced production times for repeatable high speed, high precision, seam and spot welding. The new software is a single application allowing control and management of all laser and scan head programming functions.

This product incorporates the scan head and the software, the Scan Head User Interface (SHUI), which is integrated into the powerful industry leading LaserView SETM software, enabling seamless programmability of scan head and laser parameters through a single operator screen.

The Scan Head has been designed to enhance and complement the current JK125 and JK300 series of pulsed lasers, enabling the beam to be deflected precisely and quickly throughout a range of spot sizes and working areas. Two configurations are available; the Variable Spot Size, which provides up to x2.8 beam expansion capability and can be fitted with an in line camera adaptor which will accept a standard C-mount camera, and the Fixed Spot Size which will accept a CS-mount camera fitted to the rear of the fibre output housing. A range of f-theta objective lenses are available to provide spot sizes from 100µm to 750µm and a usable working area from 25mmx25mm to 150mmx150mm.

The SHUI was developed by GSI to eradicate the need for separate programmes for the laser and scan head and has been specifically designed for laser welding applications, rather than the more traditional marking applications for which scan heads are predominantly used. This is a unique, pre-emptive and self optimising system which effectively produces two program lists from a single, user generated graphical scan head profile.

Increased productivity and flexibility

Using a scan head instead of the more conventional process-tool-based systems gives an array of advantages to the user. Processing cycle time is significantly reduced, for example.

Welding time can also be decreased using the scan head. In most welding applications the average welding time is short compared to the positioning and loading time of the system; typically the 20% to 50% of the cycle time of the process. Reducing the non-productive times with a scanning head decreases welding time by up to more than 90%.

Additionally, the shape of the weld can be programmed in a variety of geometrical shapes and figures such as circle, sine wave, open circle, and spiral, giving laser welding further structural advantage over conventional spot and MIG welding.
