Abstract
The invention provides a ship weld air-tight pumping pressure detection method and a detection device. The detection method is that: each screw plate used for detection is welded on any section A-A1 where the ship steel plate weld is required; wherein, one screw plate is connected with a detection device C1 and the other screw plate is connected with a detection device C which is used for measuring the air pressure of the weld and detecting whether the air pressure is smooth; pressure air of 0.02MPa is connected into the screw plate which is connected with the air source by a duct; soapy water is externally coated outside the weld of the whole section to be measured; the positions where the air is leaked or the bubble exists are judged as leakage point and the air pressure is released then and the leakage points are complementarily welded; the leakage is detected section by section repeatedly, and the complementary welding is carried out till that the complementary welding, detection and complementary welding process of all welds are completed.
Description
Technical field
The present invention relates to a kind of ship hull weld joint air-tight pump pressure inspection method and verifying attachment thereof, belong to boat segmental manufacture process inspection technology.
Background technology
In the shipbuilding process, the watertightness cabin checks that the method for leak source has following several at present:
1, cabin air pump pressure inspection technique: in the inflation of relevant cabin, by being coated with suds in relevant commissure, leak source is confirmed as in foaming place, then leak source is carried out repair welding;
2, weld seam vacuumizes inspection technique: by being coated with suds in relevant commissure, cover weld seam with vacuum (-tight) housing, vacuumize inspection, foaming place is a leak source.Then leak source is carried out repair welding;
3, kerosene osmosis inspection technique: be coated with swabbing lime at the surface weld place.After treating that water lime is done, brush kerosene at the back bead place of correspondence again.The leak source that is that kerosene oozes out is arranged at swabbing lime place.Then leak source is carried out repair welding.
More than three kinds of methods all be used for the different stage of shipbuilding process and according to the different diverse ways of selecting for use of working condition and regional environment.
The use of above-mentioned the whole bag of tricks can't be satisfied the requirement of whole application of segmentation and quality, only the welding quality that guarantees weld seam is lacked reliability, and the control of manufacturing progress, production cost also brought difficulty, and since when repeated labor, welding arduous working condition, safety etc. also perplexing the numerous workmans and the technician of China's shipbuilding industry always.Therefore seek a kind of practicable field welding checking method for quality, not only guaranteed the quality of cold wind, simultaneously but also can alleviate working strength of workers and obtain maximum economic benefits and just become original intention of the present invention.
Summary of the invention
