ABSTRACT:
A process and device for the laser welding of a tube (14) along its inner circumference with a probe (1) that can be inserted in the tube (14) has for the focusing and deflection of a laser beam (57) propagated within the probe (1), mainly along its longitudinal axis (10), at least one optical element (41, 65), which generates a deflected laser beam (59) focused on a focal point (F) lying outside the probe (1), the direction of whose propagation is oriented obliquely relative to the longitudinal axis (10). By this means, both the thermal stress on the deflecting elements (41, 65) mounted within the probe (1) and any precipitation of welding material in the interior of the probe (1) are reduced.
