METHOD FOR WELDING COMPONENTS BY MEANS OF ELECTRON BEAM BY MEANS OF HIGH-FREQUENCY BEAM DEFLECTION

摘要

The method for welding components by using an electron beam, which oscillates by high frequency beam deflection between a first melting bath (1) lying ahead in a welding direction (b) and a second melting bath (2) following in the welding direction, is claimed. The temporal retention times of the electron beam stands to each other in a relationship of 3:2 in the area of the first and the second melting baths. The joining surfaces of the components are melted in a first heat influence zone of the first melting bath and in a second heat influence zone of the second melting bath. The method for welding components by using an electron beam, which oscillates by high frequency beam deflection between a first melting bath (1) lying ahead in a welding direction (b) and a second melting bath (2) following in the welding direction, is claimed. The temporal retention times of the electron beam stands to each other in a relationship of 3:2 in the area of the first and the second melting baths. The joining surfaces of the components are melted in a first heat influence zone of the first melting bath and in a second heat influence zone of the second melting bath up to in a depth (C) of 60-70% related to the total depth of the components to be welded. The oscillating beam deflection takes place with a frequency of 4500-5500 Hz and an amplitude (A) of the oscillating motion in welding seam direction of 5-10 mm.
