Abstract
The method of arc welding optical fibers includes a fusion and inter-penetration first step during which the ends subjected to the arc are fused and caused to inter-penetrate, and an alignment second step so as to continue the fusion under the control of the offset that is calculated on the basis of an image of the ends, which are not externally illuminated. The first step is an arc current control step performed in successive current increments, under the control of the brightness taken on by the ends after each increment.
