The parameters of the optical scheme for the penetration of materials of large thicknesses by the radiation of high-power fiber lasers are calculated. It is shown that the ratio of the collimating lens C160 with the focusing lenses F250 and F400 gives the best optical characteristics necessary for melting materials of large thicknesses. The optimal parameters of the optical circuit are imple-­mented in the focusing system IPG FLW D50. It has been experimentally shown that the selected parameters of the optical scheme make it possible to obtain high-quality through-­melting on steels up to 12 mm thick. The preferred optical scheme for welding materials of large thicknesses should be considered the ratio with C160 / F400.
