<p>A method is described for welding a sintered molded body ( 1 ) which comprises a residual porosity and which is molten in the region of the later weld seam ( 3 ) by a laser beam ( 4 ). In order to obtain dense weld seams it is proposed that during the melting of the molded body ( 1 ) the atmospheric oxygen is bound at least substantially by a deoxidizer from the pores of the molded body ( 1 ) in the area of the weld seam and is embedded in the form of finely dispersed oxides in the weld seam ( 3 ).</p> |
