Optional extension for pulse-synchronised circumferential welding

Available for all Vision Lasertechnik GmbH beam sources

Schutzgas

Programmable shielding gas post-flooding

In order to eliminate the oxidation of the welded joint directly after it has been welded, the times during which the shielding gas ist still conducted on the welded joint following the welding can be individually set.
PWM

In the lower power range, which depends upon high stability, traditional lasers are inclinined toward a low „pulse to pulse stability“ and thus to a non-uniform welding result. The Pulse Width Modulation (PWM) gives a vastly more fine and stable coordination, as the internal energy supply here works in the area of the optimal output.
Pulse shaping

Free pulse shaping enables the setting and saving of all possible variations in the pulse process. Materials with different thermal coefficients of expansion thus show a clearly better welding behaviour - your laser´s area of application thus expands.
On axis gas

On-axis shielding gas supply

A reliable on-axis shielding gas supply enables perfect welding even with highly-sensitive materials, such as titanium, for example.

The welded joint is always flooded with shielding gas under 90 degrees. This prevents the sort of shadow effects and swirling which occurs when a lateral gas supply is used.
Rotation Axis

Specially developed turning units increase the user value of your workstation. They incorporate all functions of CAN-Step control, available at the touch of a button, including pulse synchronization and „Teach in“ programming.

Additional features: • Swivel-mounted • Free implementation up to Ø40 mm • different chuck types, chucking range up to Ø 160 mm.
Display

Large display with backlighting

The large backlit display provides the user with a direct view of all the important operating parameters. Adjustment limits are visualized.

The adjustment of the parameters themselves takes place via the work chamber´s control elements.
Can Step

Precisely controls axis movements. This extends manual welding by its sophisticated automatic and programable functions. Touchscreen and Joystick terminals directly in your workspace provide a unique, simple control concept. Thanks to the completely integrated hardware, a separate computer is not needed.
Booster

Booster technology for long lamp lifespan and heightened pulse stability The booster enables you to further raise the „pulse to pulse stability“ and to lengthen the lifespan of the flash lamp. Shortly before the shoot, the simmer power is automatically increased, thus stabilizing the plasma in the lamp and increasing the electrode temperature. This leads to a substanitially more stable energy output of the laser, especially with low energy.
Beamtuning

Beam Tuning Set

The innovative Beam Tuning Set combined with booster technology guarantees a stable output even with very low pulse energies.

This is particulary beneficial when it comes to welding extremely small parts. The spot size can be reduced to 50 μm.

This feature is available as either a fixed installation or a manually connectable option.
