Coherent to present turnkey solution for tube and profile laser welding at Tube 2020

From March 30 - April 3, 2020, TUBE in Düsseldorf/Germany, one of the world’s most important trade fairs for the tube and profile processing industry, will again offer attendees insights into the latest manufacturing technologies. In Hall 6/C03, Coherent will present its industry-proven Profile Welding System (PWS), a turnkey solution for tube and profile laser welding with an integrated process sensor for welding gap detection and intelligent seam tracking.



In particular, Coherent will highlight some new product features that enable higher quality, higher throughput, lower costs, and reduced scrap. Exhibition attendees are invited to visit the Coherent display and to discover the system’s unique advantages.

These include: 

  • A new “reverse welding” feature that eliminates any gap in the weld seam when the system is stopped and then subsequently restarted
  • The new “automatic system height focus” capability which speeds changeovers to different diameter tubes, and automatically compensates for tolerance variations in actual tube diameter or machine settings
  • Industry 4.0 ready for increased efficiency and simplified integration in modern plant concepts
  • The ability to generate defined inside weld bead when required by the application
  • Operation using an industry-proven Coherent DC Series CO2 laser, which is well-established as delivering a stable, high quality process on most metals
  • Operation using the unique Coherent HighLight-FL Adjustable Ring Mode (ARM) fiber laser, which has already shown to be particularly advantageous for use with stainless steel, and which also offers cost of ownership benefits
  • Coherent CleanWeld technology, which includes advanced process technology to provide more consistent results, i.e. through better control of melt pool dynamics with up to 80% less spatter 

Coherent applications engineers and product experts will be on hand at the exhibit to discuss customers’ requirements. Visitors to the Coherent exhibit can discover about all the benefits the advanced technology of the Profile Welding System can deliver in most tube and profile production environments.
