Embodiment 1

[0030] An electron beam centering process method for a plane circular weld seam: on the basis of the two-axis linkage of the plane coordinate system X-axis and Y-axis, the rapid and accurate centering of the electron beam of the plane circular weld track is realized.

[0031] In the electron beam centering process of the planar annular weld, after determining the track position of the planar annular weld to be welded, use general-purpose electron beam welding equipment, set the electron beam current to 0.1mA, and within 1 to 3 seconds Quickly lower the beam current and determine the position of the electron beam spot relative to the track to be welded.

[0032] The specific operational requirements for seam alignment using general electron beam welding equipment are as follows:

[0033] 1) Calibration: use the target block to confirm the relative position of the electron beam current and the center line of the scale of the general electron beam welding equipment observation sy...

Embodiment 2

[0047] The content of this embodiment is basically the same as that of Embodiment 1, and its difference mainly lies in:

[0048] In the electron beam centering process of the planar annular weld described in this embodiment, in the operation requirements of using general electron beam welding equipment for weld centering, other calibration, pre-positioning, lower beam current, and final welding methods in the prior art are adopted. Specific requirements for positioning and final completion of electron beam welding.

[0049] However, the specific content of the weld seam pair is carried out according to the embodiment 1.

Abstract

The invention relates to a centering process method for an electron beam of a plane annular welding line, wherein the electronic beam is welded along the track of the plane annular welding line based on the linkage of the axis X and axis Y of a plane coordinate system. Through the invention, the common complex centering way is simplified, quick and precise centering of the plane annular welding line is realized, the production efficiency is improved by 300%, the welding line quality is effectively improved, the filament loss of an electron gun is reduced, and the requirement on the working experiment of an operator is lowered. The process method is adopted for quickly and precisely centering and welding the electron beam of the plane annular welding line for the first time in the country; the process method is applied to the welding and production of the electron beam of various plane annular welding line parts of an aircraft engine as well as the welding and production of the electron beam of various parts of a gas turbine and other similar structures. The process method has great predictable economic value and social values.

Description

technical field [0001] The invention relates to a general electron beam welding technology, and in particular provides an electron beam centering process method for a plane circular weld seam. Background technique [0002] Various plane annular welds (typically represented by aero-engine gears) using electron beam welding have the advantages of high strength, small deformation, narrow heat-affected zone, good weld shape, and simplified process. For general-purpose electron beam welding equipment, there are two main ways to achieve electron beam welding of plane circular seams: one is to use special fixtures to rotate the parts around the center of the circular seam to be welded as the axis, but due to equipment configuration Generally, only single-station clamping and welding can be used, which becomes the cycle and cost "bottleneck" of small-diameter mass production of components. If a multi-station welding mechanism is selected, millions of yuan will be invested in design,...
