The laser allows realising spot or seam tight welding or welding of support of incomparable quality and precision on articles of simple or complex shapes. This process generates little deformation and allows operating on thicknesses from 0,05 mm to a few mm by carrying out aesthetic welding of deep penetrations.

The realization of a welding is based on the phenomenon of localised fusion of the material at the point of impact of the beam, as while an operation of cutting, except for the puddle which is not drew out but maintained. The advantage of laser welding compared to the conventional means is especially in smoothness of the welding. This allows to improve not only the aesthetic aspect but also to have a very localised heating.
