Easy welding technology, fast return of investment, affordable equipment.

Our fist steps in manual laser welding. A simple technology for welding and sealing of materials, from 0.5 mm or even thinner, and also for thicker material joining applications. To be used in metal fabrication, ventilation and conditioning, manufacture of metalic components,…
For sure many companies are going to benefit from laser welding technology, now at affordable cost of investment and very fast and easy return with faster and higher quality production.

Applications include repair of components that weld precision, minimum deformation and thermal affectation of the welded area are required.

Some examples of the results we obtain in welding on different applications:

Advantages of Laser Welding (LW) process:

  • Minimum thermal affectation (heat input) of the welded area:
    • It is possible to weld even very thin metals, with almost no deformation of the welded component
    • The HAZ (Heat Affected Zone) in minimum, and so the problems related to the metallurgical transformations of this area.
    • Hazards associated to heat are also minimized.
  • Fast Welding
  • High skill TIG welders are not required to execute perfect welds
  • Filler metal is not required, except for some applications, as cladding or rebuilding of small areas, or when joints present some gap.
  • It is possible to weld on finished surfaces, even bright stainless steel, or galvanized steel, because there is no burning of the area next to the weld bead. If needed, the weld bead can be polished (see limitation)
  • Cost of equipment has become affordable and very fast investment return, thanks to the clear advantages of the process.
  • We have a wide range of equipment. the laser technology differs depending on the process (YAG or FIBER) and the required power. We can weld with laser metal thickness up to 6 mm, with full penetration of the joint.
  • The welding torch can be used manually or can also be easily automated.
  • Safe welding, the right safety glasses with appropriate wave length filter is required. Heat associated hazards are almost not existing. No spattering. Minimum smoke production.

Limitations of the Laser Welding – LW process:

  • It is needed that the edges of the components to be joined are precisely cut and with no slag. Maximum recommended gap to avoid filler metal is ≤ 1 mm, while if filler metal is deposited, gap can be up to 2 mm:
    • The image shows a fillet weld on stainless steel: the weld bead is perfect inside and outside the corner joint, since gap was zero (0) in the full weld length. Irregular cut of the joint edges produce welds not capable to fill the joint, unless filler metal is deposited.
    • Actually, filler metal is deposited using a cold wire feeder, and it is possible to melt up to 1,6 mm wire thanks to the laser oscillation of the “Wobble“, that allows to weld slighly separated joints.
