Abstract

State of the art of welding with carbon-dioxide laser radiation is to weld steel material up to a wall thickness of 20 mm in one pass utilizing beam powers up to 20 kW. Welding material exceeding 20 mm wall thickness requires the application of multiple pass techniques. Since the process behavior deviates from the conventional deep penetration effect measures due to beam handling and shaping have to be taken into account. Within the paper the effects of beam oscillation and focused beam shaping on the process will be discussed. Experimental results concerning the influence of beam characteristics, beam handling, and wire feed on the seam quality will be presented. The experiments were carried out by means of a modern beam source with a nominal output power of 20 kW which offer the opportunity of raw beam shaping by a telescope. The material applied was a fine grain structural steel. The application of multiple pass welding with laser radiation offers great opportunities in industries dealing with materials of high wall thickness.
