Embodiment Construction

[0016] The present invention will be further described below in conjunction with the drawings and embodiments.

[0017] Such as figure 1 As shown, two steel plates are horizontally butt welded to form a welding surface 7 and a welding seam 8 on it.

[0018] In order to test the tightness of the weld 8, it is necessary to form a sealed space on the weld 8. By applying soapy water on the weld 8, the air pressure in the sealed space is reduced to a specified value. When the specified parameters are reached, soap bubbles will appear at the weld to show that the tightness of the weld is not up to standard.

[0019] Such as figure 1 As shown, the device provided by the present invention includes a weld covering box 1 and a vacuuming device 2. The weld covering box 1 and the vacuuming device 2 are connected by a pipeline 3, and the weld covering box 1 is covered on the weld 8. The welding seam cover box 1 and the welding surface 7 form a sealed space, and the vacuum device 2 is activated t...

Abstract

The invention relates to shipbuilding, and provides a weld joint tightness detecting device for a ship under construction. The weld joint tightness detecting device aims to solve technical problems that an existing weld joint tightness detecting mode for a ship under construction is labor-consuming and time-consuming, and production cycle of the ship is prolonged. The weld joint tightness detecting device for the ship under construction comprises a weld joint covering box and a vacuumizing device which are connected by a pipeline. The weld joint tightness detecting device is characterized in that the weld joint covering box consists of a cover plate and at least two welded surface support plates fixedly connected to edges of the back of the cover plate, the welded surface support plates are arranged on the back of the cover plate, and a sealed space is formed by the cover plate, welded surfaces and the welded surface support plates after the cover plate and the welded surface support plates contact with the welded surfaces with a weld joint. The weld joint tightness detecting device is reasonable in structure and convenient to use, and can test tightness of weld joints which have different shapes and are located at different positions.

Description

[0001] Technical field [0002] The invention relates to shipbuilding, in particular to a device for detecting the tightness of welds of ships under construction. Background technique [0003] The tightness test in the sub-stage of the ship under construction has always been a problem that plagues the shipbuilding industry. Usually, the watertight welds on the ship segment should be covered with tape when painting after the ship segment is produced to prevent the watertight welds from being covered by paint. After the ship section is closed on the slipway, the cabin is sealed and pressurized, and after leaks are checked and repaired, the watertight welds are repainted. This method not only affects the shipbuilding production cycle, but also repaints the watertight weld on the berth, which damages the paint layer around the weld, which requires a lot of labor, is low in efficiency, and time-consuming. Summary of the invention [0004] In order to overcome the technical problems of...
