The invention discloses a space curve electron beam welding method, comprising the following steps: pre-welding treatment; spot welding connection; clamping and alignment; generating a three-dimensional weld curve trajectory numerical control program: setting up a local coordinate system at the welding center, extracting three-dimensional welding After extracting several extraction points on the three-dimensional welding seam curve by means of equichord tolerance, the point data of the X, Y, and Z coordinates of each extraction point are obtained, and the point data of the Z-axis coordinates of each extraction point are obtained. Converted to the focus current that changes relative to the origin of the local coordinate system, converts the weld thickness of each extraction point into the corresponding electron beam current, and according to the point data of the X and Y axis coordinates of each extraction point, the focus current parameters and the electron beam current The electron beam welding program of the three-dimensional welding seam curve trajectory is programmed with parameters; electron beam welding: the electron beam welding program is imported into the control system of the electron beam welding machine, and the three-dimensional welding seam curve is electronically processed after obtaining the focusing current parameters of the origin of the local coordinate system. Beam welding.
Description
technical field [0001] The invention relates to the field of three-dimensional curved electron beam welding in space, in particular to a method for electron beam welding in spatial curved lines. Background technique [0002] On certain rotary parts, if a large-diameter mounting seat needs to be welded on the side wall, the weld seam is the intersecting line between the rotary body and the rotary body, as shown in the attached figure figure 1 As shown, it is a three-dimensional curve in space, as shown in the accompanying drawing figure 2 shown. The surface of the weld seam changes continuously with the curve, which in turn causes the change of the focal length; at the same time, due to the arbitrary intersecting angle of the two rotators, a thickness section with continuous and non-uniform changes along the intersecting curve is formed. During electron beam welding, due to the electron beam welding The mechanical axis of the machine only has two axes of X, Y and a turntab...
