  • Page 46 THE PHYSICAL PRINCIPLE OF LASER WELDING The physical principle behind the generation of laser light is the phenomenon of stimulated light emission. In fact, LASER stands for Light Amplification by Stimulated Emission of Radiation. Thus, a laser may be defined as light amplified by the emission of a chain of photons, originating from an initial photon (light particle) that interacts with an excited atomic system and stimulates the emission of two additional photons, which, in turn, interact with other atoms, giving rise to an avalanche effect.

  • Page 53: Replacing The Ar/Ar Safety Window

    REPLACING THE AR/AR SAFETY WINDOW Whenever the protective window is "dirty" the laser power output is reduced.Therefore, when there is a significant concentration of metal spatter on its surface, the glass should be replaced. Check the microscope lens protective window located inside the welding chamber at regular intervals. This special anti-reflective @ 1,064 nm glass is secured to the output of the optical path by means of an aluminium ring nut, which is, in turn, held in place by a screw.
  • Page 54 ALIGNING THE AIMING SIGHT To adjust the stereo-microscope, unscrew it from its base (Ref. D - Fig. 61), using the 2.5 mm Allen screwdriver provided, and once it has been pushed firmly against the front edge of its base, or in other words away from the operator's position, screw it down firmly so it is immobilised permanently in that position.

  • Page 55: Replacing The Cooling Liquid

    REPLACING THE COOLING LIQUID • Insert the plastic connection without the funnel (figure 62) supplied with the machine into the female connector at the bottom of the laser rear panel, figure 63. • Remove the red cap at the top (figure 62) and allow the water to drain completely from the plastic connection, tilting it downwards so that it collects in a suitable recipient.
  • Page 56 ORDINARY MAINTENANCE The instructions for carrying out ordinary maintenance on the machine mechanical parts are set out below. This type of maintenance is important to preserve the integrity of the parts that determine the precision and movement of the laser. These operations must be carried out at regular intervals since it is important to check the state of wear and tear of the mechanical parts and the integrity of the machine in general periodically.
  • Page 57 ORDINARY MAINTENANCE CONTINUED MAINTENANCE ON LINEAR MOTOR STATORS The stators in the linear motors create a magnetic field that attracts metal parts and welding residues, so it is very important that they are always clean and free from any attached particles that could compromise their correct operation.

  • Page 62: Protection Systems

    INTRODUCTION In the event that a LASER Device is installed on the system, in addition to the usual hazards deriving from the system functions and operating modes, it is necessary to bear in mind the additional hazards represented by LASER radiation (electromagnetic radiation, mainly infrared). The safety of this type of equipment is subject to specific standards, both from the electrical point of view and from the point of view of radiation (non-ionised).

  • Page 63: Special Requirements

    SAFETY The monitoring optics must be equipped with special attenuator devices capable of preventing personnel from accessing radiation levels in excess of class I AEL. This is particularly important in the case of systems fitted with inspection windows for viewing the interaction between the LASER beam and the process material.

  • Page 64: Residual Risks

    SAFETY RESIDUAL RISKS THAT THE USER MUST IDENTIFY AND ELIMINATE These are risks deriving not from the LASER itself but from its use. In fact, associated with the main radiation, are collateral infrared and ultraviolet radiation, which, due to their intensity, may represent a potential hazard.
