Laser safety: Laser protection class 4 applies to our Wobble manual laser welding equipment when in operation.

Different measures are therefore required on the customer side to ensure laser safety, such as the appropriate training of employees, wearing special protective equipment and setting up a separate laser safety area.

MOBILE LASER WELDER USED WITHOUT ENCLOSURE

High-power Laser Used without Enclosures

It is possible to use industrial lasers without enclosures!

However, in order to make them  safe to use, personal protective equipment must be used (laser safety glasses) and access to the surrounding area needs to be controlled by interlocks or other means.
Special signage is required and other procedures must be implemented to enforce the laser-controlled area.

Danger of Laser radiation

Lasers used for welding applications radiate inthe infrared spectra, which are not visible to the humaneye.  The intensive fiber laser light radiate in the visible spectrum but invisible for humans, is especially dangerous to the eye. Fibre laser radiation penetrate through to the retina which can be destroyed irrevocably by relatively little radiation.
Misdirected laser radiation can come directly from the laser and threaten the eyes as a result of a faulty parameter setting, an opened cover, a displaced mirror etc. Other hazards include skin burn or inflammation from combustible materials as a result of misdirected laserradiation. The greatest hazard, however, usually stems from reflected laser radiation: the major share of the laser radiation is reflected by coldmaterial first. To this we can add reflections of work piece edges, as a result of turbulence in the weld pool etc. 
Misdirected radiation and reflections must be blocked off. That is why the law stipulates that the laser beam and the work zone must be in an enclosure. Beyond that, all those present, and the machine operators in particular, should wear protective goggles that are appropriate for the laser radiation being used.  Fbre laser radiation are very dangerous to the eye and require special protective measures andapproved safety goggles.

Standard protective goggles made of glass or acrylic glass are not suitable at all,

as glass and acrylic glass allow fibre laser radiation to pass through!

Rules of conduct on the safe use of lasers

The following rules are of particular importance:

  • Never point the laser beam at anyone’s eyes!
  • Do not look directly into a laser beam!
  • Always wear protection glasses!
  • If the laser light accidentally strikes your eyes, close your eyes and immediately move your head out of the laser beam.
  • Do not use any focusing optical device to look at the laser beam while working with lasers.

Danger of Welding emissions

Depending on the materials being welded, laser welding may generate fumes, altough much less than any other welding process, that are hazardous to health.

Therefore, it is important to always provide sufficient extraction and fresh air.

When is your laser welding machine conform to the CE regulations?

You need to respect minimal following CE regulations!
