A PROCEDURE THAT ALLOWS YOU TO OBTAIN A LASER SOLDED PRODUCT AND A LASER SOLDED PRODUCT.

摘要

A method of welding a first and a second element to each other by transmitting radiation in a predetermined direction to an interface between the two elements, the method comprising: 1. providing the first element having, in the direction, a first layer and a second layer connected to each other, the first layer having a first absorption coefficient, mia1 0.4 mm-1, at a wavelength of radiation and the second layer having a second absorption coefficient, mia2 0.1 mm- 1 at the wavelength, 2.provide the second element with, in the direction, a third absorption coefficient, mia3, at the wavelength, the third absorption coefficient being less than the first and second absorption coefficients, 3. place the second element to be contiguous or be close to the first layer and so that the radiation penetrates the second element, along the direction, before penetrating into the first layer, character Adopted by 4. Provide a third layer that has a scattering coefficient, more than 0.4 mm-1, at the wavelength, between the first and second layers, in the direction of radiation, and 5. provide radiation to along the direction, the radiation: - penetrating the second element, - heating the first layer to weld the first layer to the second element, and - the radiation that has penetrated the first layer being dispersed by the third layer.
