Welding time statistical method based on welding modeling

Abstract

The invention relates to a welding time statistical method based on welding modeling. The method comprises the following steps: S1, establishing a welding groove standard library; s2, establishing a welding knowledge base; s3, creating a ship body structure welding model; s4, creating a welding man-hour calculation method; and S5, generating welding object quantity and man-hour statistical theoretical data. According to the method, the hull structure welding seam length and the welding joint form and the welding position of each welding seam are accurately counted through the hull structure welding model, the accuracy of estimating the welding object amount is improved, the working intensity of counting the welding object amount and the welding time is reduced, and the ship building period is shortened.

Description

technical field [0001] The invention relates to the technical field of ship design and construction, in particular to a welding man-hour statistical method based on welding modeling. Background technique [0002] Ship production welding man-hours refer to the length of the welded seam and the time spent by a single welder to complete a single welding task during the ship construction process. The man-hours spent by shipyards in shipbuilding welding account for about 1 / 3 of the man-hours for hull structure construction, and 1 / 6-1 / 5 of the total man-hours for shipbuilding. Accurately formulating the welding man-hour quota is an important basic work for controlling the entire shipbuilding cycle and cost. In recent years, my country has entered the ranks of the world's largest shipbuilding countries, and the welding technology of ships has also undergone major changes. The semi-automatic or automatic gas shielded fillet welding process has been adopted for the assembly and weld...

Problems solved by technology

This method relies heavily on the accuracy of reported data and relies entirely on manual work. It is difficult to make comprehensive statistics when production is fully advanced, and there are still problems of untimely and inaccurate data statistics.

[0005] However, the method of calculating the welding production efficiency based on the daily consumption of welding materials per welder and estimating the total welding man-hours of product construction from the welding material consumption can only grasp the overall man-hours from a macro perspective, which is too broad and not accurate enough.
