CHAPTER 2 SAFETY In this charter are discussed matters about the individual safety. The performed tests demonstrate the safety and the laser reliability when is used properly. It is however necessary that the operator is informed about the precautionary standards ready to avoid possible damages to people or to the same machine. -
Page 12: Laser Radiation Absorption
2.1 LASER RADIATION ABSORPTION The human tissue absorbs the electromagnetic radiation in different way in accordance with the wavelength of the same radiation. Both the eye both the skin have their “presetting” to accept some wavelengths and they are more refractory to absorb others. In the eye specific case, the cornea and the crystalline let pass and reach up to the retina, also with different attenuations, all the wavelengths that go from 400 to 1400 nm, or range between the light in the visible up to the infrared IRA. -
Page 13: Classification And Dangerousness
2.2 CLASSIFICATION AND DANGEROUSNESS The regulation has established different lasers dangerousness classes on the basis of their ability to produce damages to people from laser in class I (essentially safe in every condition) to the laser of class IV dangerous in different conditions. The laser of class III show the label “ATTENTION ”... -
Page 14: Radiation Vision Conditions
2.3 RADIATION VISION CONDITIONS The laser to the resonator exit is to be considered as a monochromatic light source highly corresponded and intense. For these characteristics it can be seen as a “Punctiform source” of great brightness. This allows that its “image” is after focused on the Retina in one very small spot with power density dangerousness high! If instead the beam becomes divergent and spreads on a not reflecting screen, then there will be a “large vision”... -
Page 15: Risks For The Eyes And The Skin
2.4 RISKS FOR THE EYES AND THE SKIN The cornea and the retina, if submitted to an intense laser radiation, also of short duration, or to a less intense radiation but of long duration, can burn and can be damaged in irreparable way forever. - Page 16 NOTE Don’t submit to the laser radiation materials different from those for which the machine has been manufactured The haviest collateral risk, being able to result fatal, associated to a laser device is surely represented from the electricity. This fact can happen when the warnings and the procedures imposed from the machine manufacturer aren’t respected.

Page 23: Layout And Machine Description
4.3 LAYOUT AND MACHINE DESCRIPTION The physical principle that is the basis of the laser light generation is the phenomenon of the light stimulated emission. LASER in fact is the acronym of Light Amplification by Stimulated Emition of Radiation. It means that the laser is light amplified from a chain photonic emission, originated from a first photon (light particle) that interacting with an excited atomic system, stimulates the emission of two photons and these ones interacting with other atoms give rise to an avalanche effect. -

Page 35: Change The Protection Slide Ar/Ar
7.1 CHANGE THE PROTECTION SLIDE AR/AR Every time that the protection slide is “dirty” is noted a reduction of the delivered power. So, to the presence of a strong concentration of metal sprays on its surface change the slide. Check periodically the protection slide of the microscope lens that is placed inside the welding room. -
Page 36: Realign The Pointing Cross
7.2 REALIGN THE POINTING CROSS It can happen that the pointing cross for the welding isn’t aligned to the effective shot point. This could verify all times that the welder is moved or lifted. Also a knock to the microscope could create the pointing cross misalignment from the effective shot point. - Page 37 Picture 19: Fastening of the Stereomicroscope So to verify the alignment, put in steady way with focus vision a sheet metal piece inside the welding room. And then hit with a low power single shot the sheet metal placed before. Looking so inside the microscope, rotate with small movements the screws 1 and/or 3 (Fig.18) up to the cross overlapping with the point where the shot has hit the sheet metal.
