ALW

Laser welding in the manufacturing environment
without additional security measures

Closed Laser Welding Device ALW

The ALW is a comfortable, ergonomic, and compact seated workstation that offers plenty of legroom, and which can be adjusted to the height of the operator via
the height-adjustable foot plate. The observation lens offers a variable viewing angle from 10° – 50°, thus ensuring
comfortable working. The closed, laser-proof housing makes the ALW a laser-protected workplace that can be used in a
normal production environment without additional safety precautions.

Easy to Use

The laser system is easy to operate. In addition to configuring via the display, the laser parameters can be adjusted
via the patented multifunction footswitch or adapted accordingly during welding.

The large doors of the ALW can be opened wide. This facilitates easy loading.

The ALW in a few words:

  • Robust housing, also well suited for automatic, programmed laser welding
  • Ergonomic seated workstation for fatigue-free working
  • Closed system, thus usable in any room
  • Precision joystick for optimal work results
  • All-in-one system (table, laser, extraction, safety)
  • Plenty of space inside and wide opening doors
  • Easy to operate
Advantages

Precise Movement System

A large and stable work plate holds workpieces weighing up to 350/400 kg and ensures their precise positioning.
The joystick for movements along the X, Y, Z, and R axes reacts very accurately. All axes directly follow the joystick movement.

Movements are made

  • manually by joystick,
  • semi-automatically,
  • or in automatic mode (ALW 200/300) programmed with the WINLaserNC software.

WHICH ALW IS RIGHT FOR YOUR APPLICATION?

ALW 100/150

The ALW 100/150 is recommended for repair welding and material application in tool and mold manufacture. With this laser power, all common tool steels can be welded easily and with very good results.

ALW 200/300

The ALW 200/300 enables programmed series production and welding on materials that are difficult to process, such as aluminum, precious metals, titanium, or sensitive alloys. It can be used for welding wires from 0.2 to 0.8 mm. Automatic wire feeding (LAFet) can be installed. Included in the scope of delivery of the ALW200/300 is the Ergotubus, which ensures the ergonomic alignment of the microscope.

This system allows you to work pulsed at up to 100 Hz under visual control.
