It is monitored again, makes camera lens just to monitored area as far as possible in monitoring；
When the 7th, being monitored inside the insertion of camera lens 4 monitoring object, the temperature of internal area to be monitored must be in tolerance zone
It is interior, to avoid the damage of CCD lens assemblies；During monitoring, its radiation source intensity is also adjustable, in favor of the operation of endoscopic
The observation of personnel and shooting defect image；
8th, the best fit of LED, adjustment LED and CCD camera lenses is opened, it is ensured that the picture on televimonitor is clear；
9th, generally, the mobile monitoring speed of camera lens 4 is no more than 10mm/s, should make image balance, beneficial to observation；
Large area should use rectilinear scan pattern when sweeping survey, and survey width is swept every time and is no more than 20mm, the observation model of camera lens 4 is also must not exceed
Enclose；
Tenth, weld monitoring personnel should prevent camera lens 4 from occurring to bear energy more than it between extraneous hard thing in the case of accident
The violent shock of power；
11, the butt weld that need to carry out high-pressure gas double-wall pipe weld monitoring system monitoring according to design technology requirement is entered
Line flag；
12, Treatment Analysis is carried out using the image of 8 pairs of collections of televimonitor, after weld monitoring is finished, prison should be provided
Observe and predict announcement；
13, high-pressure gas double-wall pipe Butt welded seam performs inspection according to relevant criterion, is deposited not in the root of weld
In crackle, incomplete penetration defect；The excessive defect that weld seam is present, operating personnel should record the image of the defect in time, and be subject to
Numbering, after need to confirming to poor weld through relevant departments, can carry out soldering；After Weld Seam Repairation, 4 pairs of camera lens should be also used
The weld seam re-starts endoscopic, final check and accept and record again；
14, after monitoring terminates every time, it is necessary to clean camera lens 4 using 70% spirit solvent, and arrange instrument, scene.
In summary, high-pressure gas double-wall pipe weld monitoring system of the present utility model, simple in construction, method is simple, inspection
Look into rapid, with low cost, reliability high.Can the welding of real-time monitoring tubular road when appearance of weld quality, and in face of weld
After cleaning out, presentation quality inspection can be carried out to the surface of weld seam and its heat affected area immediately, can detect in real time is
It is no to there is such as surface pores, undercut, overlap, crackle, incomplete fusion, incomplete root penetration, root protrusion surface defect；So that weldering
Seam defect can be found in time, be eliminated early, so as to improve the success rate of strength test and leak test, saving is constructed into
This, saves the time.So, the utility model effectively overcomes various shortcoming of the prior art and has high industrial exploitation value
