Abstract

The invention provides an electron beam welding parameter determining method and device. The method comprises the steps that in the welding process, the focusing current gradually and linearly decreases from the maximum value to the minimum value and from the start point to the terminal point of a weld joint; according to the focusing current corresponding to the start end of the narrowest part of the weld joint and the focusing current corresponding to the terminal end of the narrowest part of the weld joint, the welding focusing current corresponding to the current beam value and the welding speed is determined; welding focusing currents of test welding plates of the same material and same thickness are obtained under different beam values and/or different welding speeds; the beam value, the welding speed and the welding focusing current corresponding to the condition of meeting the preset requirement are selected as electron beam welding parameters needed when a welding plate of the current material and thickness is welded. The technical problem that as no simple and effective welding parameter determining method exists in the prior art, the welding effect is poor is solved, the purpose of accurately and effectively determining the welding parameters is achieved, the process test time is shortened, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a method and device for determining electron beam welding parameters. Background technique [0002] In the fields of aviation, aerospace, ships, oceans, etc., in order to meet the needs of low-cost, lightweight, and integrated manufacturing, electron beam welding is one of the key manufacturing technologies for large-thickness material structures. Focusing current is one of the key welding parameters in electron beam welding. When the focus current is improperly selected, for electron beam welding of large-thickness structures, it is easy to cause welding defects such as incomplete penetration, weld cutting, and poor surface formation. [0003] Usually, using the electron beam welding process test method, the conventional process test methods for obtaining suitable welding parameters such as focusing current mainly include the following types: [0004] 1) Establish the relatio...
