Abstract

The invention discloses a vacuum welding seam airtight detector which is characterized in that: the detector comprises a vacuum sucker and a vacuum device, the vacuum sucker is communicated with the vacuum device through an adapter, and a body of the vacuum sucker is partly or completely transparent. The invention discloses a weld seam airtight detection method which comprises the following steps: (1) applying solution containing a foaming agent to a weld seam; (2) placing the sucker at a weld seam surface area; (3) carrying out vacuum-pumping on the sucker to allow the sucker to adhere to the weld seam surface area; (4) through the sucker, observing whether a bubble rises at the weld seam or not, and if so, determining that weld seam airtight has problems, otherwise determining that the weld seam airtight is good. The body of the vacuum sucker is partly or completely transparent in the above steps. The weld seam airtight detection method uses the vacuum welding seam airtight detector of the invention, and detection of the weld seam airtight is simple and effective.

Description

A kind of weld joint air-tight property detection method and employed vacuum weld joint air-tight detector
(1) technical field:
The present invention relates to a kind of weld joint air-tight property detection method and employed vacuum weld joint air-tight detector.
(2) background technology:
The close property of boats and ships is divided from principle, can be divided into close property in cabin and the close property of structure.The close property in cabin is a whole notion, the close property in a cabin, and directly can influence be safety of ship and reaches the vessel stability requirement.The close property of the structure of boats and ships is a local notion, and it is a key factor, and directly to the whole close property formation restrictive function of boats and ships, the meaning of generation also is important.The subject matter that influences the close property of boats and ships is the quality of weld seam.How to detect the quality of weld seam? How define the opportunity of weld seam detection? Be the important topic of Modern Shipbuilding, it directly influences the formulation and the manufacturing schedule of the production schedule.To the impermeability of weld seam, research and develop new frock, be a new direction of shipbuilding development.The problem that detects of weld joint air-tight seems and becomes more and more important thus, accomplishes in each item production schedule that this problem can make formulation the weld joint air-tight property of segmentation is fulfiled ahead of schedule, and then reduce shipbuilding period.According to the condition of production of each shipyard,, segmentation accomplishes the detection of butt welded seam when assembling or the detection of completion butt welded seam before the building berth in segmentation, with the workload of reducing building berth greatly, reduce the cross-operation of construction simultaneously, reduce the influence of construction aspect.At present, the multi-functional towboat of construction, in bulk of outside plate is big, and the watertight weld seam of manual welding accounts for the overwhelming majority.And the watertight weld seam need carry out tightness test.Whether qualified tightness test be inspection weld seam important assessment method, and the close property of outer plate welding seams under water particularly is related to the safety after the ship launching.Do when doing the close property in cabin though this type of tightness of welding lines can close up the stage greatly at building berth, this can be deferred to the building berth stage with painting operation of this type of welded seam area, causes very big difficulty to production operation, influence berth period, brings tremendous economic loss.
Traditional tightness of welding lines detection method has:
1, is coated with kerosene at weld seam.Characteristics: easy to operate, but effect observation is not obvious, and the time is longer.
2, X-ray, UT.Characteristics: cost is higher, if every weld seam all carries out the method detection of X-ray, UT, workload is bigger, and operation is comparatively complicated.
For this reason, being necessary to design a kind of convenient and practical detection method and the close property of pick-up unit butt welded seam detects.
(3) summary of the invention
First purpose of the present invention is a kind of vacuum weld joint air-tight detector of handled easily.
A kind of vacuum weld joint air-tight detector is characterized in that: comprise a vacuum cup and a vacuum equipment, described vacuum cup is taken over vacuum equipment through one and is connected, and the disk body of vacuum cup is local or all be transparent.
Above-mentioned a kind of vacuum weld joint air-tight detector, it is characterized in that: vacuum cup is equipped with a vacuum meter, is used to detect the air pressure of vacuum cup inner chamber.
Above-mentioned vacuum equipment is a vacuum generator.
Second purpose of the present invention is to provide a kind of weld joint air-tight property detection method.
This a kind of weld joint air-tight property detection method is characterized in that step is following:
1) applies the solution that contains frothing agent to weld seam;
2) vacuum cup is placed on the face of weld zone;
3) vacuumize to vacuum cup, make vacuum cup be adsorbed on the face of weld zone;
4) see through vacuum cup observation vacuum cup binding domain, whether weld seam is heaved has bubble, and heaving like the commissure has bubble, then judges weld joint air-tight property existing problems; Do not heave bubble like the commissure, judge that then weld joint air-tight property is good;
The described vacuum cup disk body of above-mentioned steps is local or all be transparent.
The invention has the advantages that: weld joint air-tight property detection method of the present invention has been used vacuum weld joint air-tight detector of the present invention, and the impermeability that detects weld seam is simple and effective, and cost is low, easy to operate, and labour intensity is low, and the activity duration is short, and efficiency is high.

Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the user mode reference diagram of vacuum weld joint air-tight detector of the present invention.
Fig. 4 is the A-A cut-open view of Fig. 3;
Fig. 5 is the B-B cut-open view of Fig. 3.
(5) embodiment:
With reference to figure 1~Fig. 3, a kind of vacuum weld joint air-tight detector comprises a vacuum cup 1; A vacuum generator 2 connects vacuum suction 1 through taking over 11, is used for vacuum cup is vacuumized.The disk body of vacuum cup is local or all be transparent, and vacuum cup is equipped with a vacuum meter 3, is used to detect the air pressure of vacuum cup inner chamber.With reference to figure 3~Fig. 5, during use, vacuum cup is placed on weld seam 4 surf zones.
With reference to figure 3~Fig. 5, be that the present invention utilizes above-mentioned vacuum weld joint air-tight detector to carry out the detection of weld joint air-tight property, the method step of detection is following:
1) execute the solution that contains frothing agent to weld seam, the described solution that contains frothing agent can be suds;
2) vacuum cup with vacuum weld joint air-tight detector is placed on the face of weld zone;
3) vacuumize to vacuum cup with vacuum generator, make vacuum cup be adsorbed on the face of weld zone;
Whether have bubble, heaving like the commissure has bubble, then judges weld joint air-tight property existing problems, does not heave bubble like the commissure, judges that then weld joint air-tight property is good through the transparent region of vacuum cup if 4) observing weld seam heave.
The foregoing description is a preferred embodiments of the present invention; But embodiment of the present invention is not limited thereto; Other are any not to deviate from change, the modification done under spirit of the present invention and the principle, substitute, combination, simplify, and is the substitute mode of equivalence, all within protection scope of the present invention.
