are laid parallel to a transverse line 23 the transverse line 23 is preferably oriented transversely to the longitudinal direction 20 of the surface 4 415 the weld beads 33 u2032 33 u2033 preferably start at one end e g 40 of the surface 4 415 and extend in a straight line if the welding track leaves the outer contour 7 then the deposition process is shifted to the next welding track which is displaced by a defined distance in the regions in which the cavity 6 exists no material is deposited so that the transverse line 23 or parallels to it only represent s the progress of the relative movement between substrate 120 and welding head not shown in the first weld layer the surface 4 415 which is to be coated with material is created completely with parallel extending welding tracks 33 the welding tracks are shifted preferably continuously from one side in this case 40 412 to the other side in this case 409 fig4 in a second step a second weld layer of welding tracks which are laid parallel to a longitudinal line 20 26 29 is created wherein the longitudinal line 20 extends transversely to the transverse line 23 especially at an angle of 70 u00b0 to 110 u00b0 rather especially 80 u00b0 to 110 u00b0 to the transverse line 23 the longitudinal line 20 preferably extends perpendicularly to the transverse line 23 in this case also the lines 26 29 only represent the.
