3D laser welding system for highly demanding tasks in the cleanroom

A new laser welding system for 3D applications is currently being set up at RJ Lasertechnik.

This means that, for the first time, three-dimensional welding paths can be produced with the greatest possible accuracy. The focus here is on semiconductor technology and products from sensor technology.

A new, cleanroom-compatible laser welding system for 3D applications is currently being set up at RJ Lasertechnik. The machine foundation consists of a granite portal structure that ensures high thermal and mechanical stability. All axes are made of nickel-plated investment casting or anodised aluminium, gear-free linear motors or torque motors form the drive technology. This means that maximum accuracy and dynamics are combined with a long service life for all system components. The trailer frame, as well as the complete machine housing, are made of stainless steel, making them ideally suited for use in cleanrooms. As early as the construction phase, the components used were repeatedly checked for their cleanroom suitability.

The components are fixed on specific workpiece carriers and clamped and positioned with an accuracy of a few µm in the machine using a zero point clamping system. The mechanical travel paths of the system are X1000 Y600 Z400, together with two CNC rotary axes. The largest 3D body can have dimensions of X 500 Y500 Z250 mm. The expected path accuracy of the laser system is a maximum tolerance of 20 µm.
