Pipes and profiles laser welded reliably
A pipe, tube and profiles laser welding system uses an 8kW CO2 slab laser with an integrated camera for seam tracking, which can detect even the slightest discrepancies in the seam position.
The Laser Macro department of the Rofin Group will be showing an 8kW CO2 slab laser in its Profile Welding System (PWS) with automatic seam tracking at Tube 2006, Dusseldorf, Germany, on 24-28 April 2006 Together, they form a complete system for welding pipes and profiles

Laser marking system processes 1000 units/min
Laser marking system uses dual axis scanning technology to mark small and large characters on packaging lines at speeds in excess of 1000 containers per minute.
High beam quality pulsed YAG profiles finely
In medical device manufacture, pulsed Nd:YAG lasers now can do the work of profiling increasingly finer, structures.
This non-contact system will be demonstrated with the new arrangement of the tracking camera fitted directly onto the moving part of the focusing module.
This new arrangement makes it possible, among other things, to change the rolling forms without adjustment and thus reduces system down times.
Sensors for gap position recognition and seam tracking can detect even the slightest discrepancies in the seam position.

A manually-loaded turnkey laser welding system is ideal for where positioning speed and accuracy are critical for small components.
Welding solution makes laser integration easy
Pulsed YAG lasers, fitted with dynamic beam positioning, offer an easy package to integrate into production automation equipment for the automotive and other industries.
This ensures that the laser beam always follows the seam, guaranteeing high process reliability.
Thanks to high- speed precision linear drives, PWS achieves position accuracies of up to 20 micron at a production speed of up to 60m/min.
Standardised interfaces and compact dimensions enable simple integration into existing systems.
The Programmable Logic Controller (PLC) in the system can also take on additional functions, such as controlling the gases required for the welding process or the laser performance.
Specific customer requirements, such as documentation of process data for quality monitoring purposes, can be integrated on an optional basis.
The movable control panel, which is attached to a support arm, gives the users a quick, clear and central way of monitoring the system parameters and functions.
* Rofin Profile Welding System - depending on the nature of the application and the specific customer requirements, the PWS can be fitted with specially optimised nozzle sizes to achieve the best possible application results.
For example, the weld head, which swivels about 30 deg, allows drag welding, which optimises the process for high speeds.
In order to capitalise on the full potential of PWS, most of the lasers used are high-performance units with excellent beam quality.
The CO2 Slab Lasers in the Rofin DC range are unbeatable in this field.
Rofin will be demonstrating the DC 080 W at Tube, the latest development in the tried and tested range of slab lasers.
The laser on show is the 'compact' version with integrated control cabinet.
With 8kW output power and an excellent beam quality of K 0.9, this laser really proves its worth at high process speeds, where it can be used for welding pipes and profiles, amongst other things.
* Slab Laser DC 080 W with output performance of 8kW - for applications which need wider welded seam widths, the DC 080 W is also available with an optional 'Donut' mode.
This mode enables a focus diameter which is enlarged by a factor of 2 while keeping the focusing length the same.
This means an increased melted volume in order to compensate component tolerances.
Like all the other lasers in the DC product range, the DC 080 W is an exceptionally low-maintenance, service-friendly and thus highly economical laser.
The lasing gas in the resonator only needs to be replaced every 72h, which significantly reduces gas consumption.
As well as the wear-free diamond window where the beam exits the resonator, the absence of transmissive optics helps to reduce the maintenance levels significantly. Request a free brochure from Rofin-Baasel UK ...
