Abstract

The invention relates to a weld joint expression method based o. The method is used for expressing information of weld joints among parts in a workpiece, and comprises the following steps of: S1, establishing a three-dimensional model of a workpiece in three-dimensional design software, and carrying out collision check on part models in the three-dimensional model to obtain a closed geometric wireframe; formulating a screening condition, and screening out a geometric wireframe needing to be calculated; formulating a weld joint model generation rule, and obtaining a weld joint model on a geometric wireframe needing to be calculated; S2, generating a weld joint node on each weld joint model, and storing a welding information table in each weld joint node, wherein the welding information tables at least comprise parameter items such as weld joint types, weld joint stages and weld joint lengths; S3, editing welding information tables of all the weld joint models, and determining numericalvalues or information of parameter items in the welding information tables; and S4, formulating a weld joint color display rule, classifying the weld joint models according to the weld leg heights ofthe weld joint models, and displaying the weld joint models by adopting different colors for different classifications.

Description

technical field [0001] The invention relates to the field of mechanical welding, in particular to a three-dimensional model-based welding seam expression method. Background technique [0002] In the production and construction process of ships, welding operations occupy an extremely important position, directly affecting the quality of ship construction. At present, in the shipbuilding industry, the quantity of welds is counted in the form of tables, and on-site construction personnel mainly carry out weld construction based on the weld information on the two-dimensional drawings. The weld seam information under this expression is more complicated, and needs to include many different weld seam information such as the height of the welding leg, welding method, welding posture, current and voltage, etc., which is not clear and intuitive enough. In addition, the weld seam view is relatively partial and one-sided, lacking an overall perspective, and prone to human errors. Fina...
