Claim 1
Independent Claim
139 words
THE METHOD OF PRODUCING A WELD ZONE OF DESIRED CROSS SECTIONAL SHAPE WHEN WELDING WITH A BEAM OF CHARGE CARRIERS, THE INTENSITY OF WHICH IS SUFFICIENTLY HIGH TO CAUSE BEAM PENETRATION DEEPLY INTO THE MATERIAL AND TO MELT A SUBSTANTIALLY V-SHAPED ZONE, COMPRISING FOCUSING A BEAM OF CHARGE CARRIERS ON THE WELD ZONE, AND PERIODICALLY TILTING THE BEAM ABOUT AN AXIS LYING ON THE SURFACE OF THE MATERIAL AND EXTENDING IN THE DIRECTION OF THE WELD SEAM SO THAT THE ZONE MELTED BY THE BEAM SWEEPS FROM A FIRST POSITION COINCIDING WITH ONE EDGE OF SAID DESIRED ZONE TO A SECOND POSITION COINCIDING WITH THE OTHER EDGE OF SAID DESIRED ZONE, SAID ONE EDGE AND SAID OTHER EDGE BEING SUBSTANTIALLY PARALLEL, SAID BEAM SWEEP TAKING PLACE WITH SUBSTANTIALLY NO RELATIVE BEAM MOVEMENT IN THE DIRECTION OF THE WELD SEAM.
