Abstract

The invention discloses a device for testing the airtightness of a weld joint on a ship surface and a using method thereof. The device comprises an outer frame of which the lower end face is matched with the ship surface, wherein the top end of the outer frame is sealed and provided with an organic glass plate; the edge of the lower end face of the outer frame is connected with a rubber strip; and the organic glass plate is provided with a vacuumizing pipe orifice. The device can be used for the in-situ inspection of the quality of the weld joint to effectively reduce workload of re-derusting production of a component segment left uncoated as required by a segmental airtight weld joint after segment joint and workload of painting construction, reduce paint waste and create a necessary condition for meeting the requirements of a standard specified in IMO Standards for Coating Performance that the damage area of a ballast tank should not exceed 2 percent after segment joint, so the device can be widely used in the in-situ inspection of the quality of weld joints, particularly the segmental tests of pre-sealed weld joints on large-curve segments such as ship head and ship end.

Description

A kind of verifying attachment and using method thereof that is used for the ship hull surface weld joint air-tight

Technical field

The present invention relates to a kind of inspection technology of boat segmental manufacture process, specially refer to a kind of verifying attachment and using method thereof that is used for the ship hull surface weld joint air-tight.

Background technology

Along with closing on day by day of implementing of IMO " ballast tank protective finish performance standard " (being called for short PSPC); and that the damaged area after how resolving ballast tank and closing up can not surpass a difficult problem of 2% is also extremely urgent; we are except improving hull structural integrity, improving hull making precision and the raising segmentation advance fitting-out rate; finish the pre-close property welding test of segmentation before the segmentation application, improving segmentation application integrality also is crucial and an important ring.For in the less pre-close property welding test of gentle curve, we are ballast tank air pump pressure inspection technique normally: in the indoor inflation of associated ballast tank, by coating suds in relevant commissure, leak source is confirmed as in foaming place, this method of inspection can't reach the requirement of whole application of segmentation and quality, thereby the control to manufacturing progress, production cost also brings difficulty, and increased shipbuilder's repeated labor, therefore seek the research schedule that a kind of practicable field welding passer has been put on people.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of practicable field welding passer.

Another object of the present invention is the using method that a kind of above-mentioned verifying attachment will be provided.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of verifying attachment that is used for the ship hull surface weld joint air-tight, it comprises the housing that lower surface and ship hull surface cooperatively interact, the end sealing of described housing is equipped with poly (methyl methacrylate) plate, and the edge, lower surface of described housing is connected with rubber strip, and described poly (methyl methacrylate) plate is provided with and vacuumizes the mouth of pipe;

The above-mentioned using method of stating verifying attachment, its step is as follows:

A) verifying attachment of selecting for use housing lower surface and curved surface welding position to cooperatively interact;

B) connect vacuum pump on the mouth of pipe vacuumizing of verifying attachment;

C) waiting that testing the curved surface welding position coats suds or liquid detergent;

D) verifying attachment is close on the outside plate of institute's pilot seam section, and guarantees that rubber strip 3 closely contacts with outside plate;

E) start vacuum pump at last, make the pilot seam section be in vacuum state, observe the weld joint air-tight situation by organic glass.

The invention has the beneficial effects as follows: this product can the butt welded seam quality carry out field test, effectively minimizing need be reserved not application because of the close property of segmentation weld seam and cause workload and the paint application workload that eliminates rust again and produce behind the segment folding, but also reduced the wastage that paints, can not create necessary condition for satisfying IMO " coating performance standard " above 2% standard-required about the damaged area of ballast tank behind the segment folding simultaneously, thereby can be widely used in the field test of weldquality, especially on the pre-close property welding test for some segmentations of bigger segmentation of curve such as bow stern.

Description of drawings

The present invention is further described for following accompanying drawing.

Fig. 1 is the structural representation of this verifying attachment;

Fig. 2 is the upward view of Fig. 1.

Embodiment

With reference to Fig. 1, Fig. 2, a kind of verifying attachment that is used for the ship hull surface weld joint air-tight, it comprises the housing 1 that lower surface and ship hull surface cooperatively interact, the end sealing of described housing 1 is equipped with poly (methyl methacrylate) plate 2, adopt set bolt 4 to be tightly connected between described housing 1 and the poly (methyl methacrylate) plate 2, certainly also can adopt other the mode that is tightly connected according to actual needs, the edge, lower surface of described housing 1 is connected with rubber strip 3, described poly (methyl methacrylate) plate 2 is provided with and vacuumizes the mouth of pipe 21, and the described mouth of pipe 21 that vacuumizes is provided with tensimeter 22.

The using method of this product, step is as follows:

A) verifying attachment of selecting for use housing 1 lower surface and curved surface welding position to cooperatively interact;

B) connect vacuum pump vacuumizing on the mouth of pipe 21 of verifying attachment; Selecting air pressure for use is the vacuum pump of 3~4Mpa, and the TD of vacuum pump is 6 millimeters,

C) waiting that testing the curved surface welding position coats suds or liquid detergent;

D) verifying attachment is close on the outside plate of institute's pilot seam section, and guarantees that rubber strip 3 closely contacts with outside plate;

E) start vacuum pump at last, make the pilot seam section be in vacuum state, observe the weld joint air-tight situation by organic glass 2, described evacuated pressure is :-0.08Mpa; For there being the foaming phenomenon to show that weld seam has leakage need carry out repair welding.

This product can the butt welded seam quality carry out field test, effectively minimizing need be reserved not application because of the close property of segmentation weld seam and cause workload and the paint application workload that eliminates rust again and produce behind the segment folding, but also reduced the wastage that paints, can not create necessary condition for satisfying IMO " coating performance standard " above 2% standard-required about the damaged area of ballast tank behind the segment folding simultaneously, thereby can be widely used in the field test of weldquality, especially on the pre-close property welding test for some segmentations of bigger segmentation of curve such as bow stern.
