Can anyone tell me what positioning and secondary positioning are?

Secondary positioning·· Commonly known as reset··· The first positioning is to draw the margin·· The second positioning is segmented closure positioning·· Need to burn positioning welding·· Secondary positioning mainly depends on your segmentation margin·· Some segments do not have a margin and do not need to be repositioned·· You can do it all in one go·· A positioning needs to be considered from the processing of the plate··· You can't do it without a certain technology·· View the original post

The first positioning is to basically put the segmentation in place, draw some lines, and then loosen the car, and then the margin is done, and then the second positioning. However, many shipyards are now able to close the section without margin. Sectional completion inspection has key data records**, which is the so-called "precision control", but at present, we can only achieve the middle straight segment of the no margin closed, the beginning and end of the section, due to the segmentation of the production of the construction team is not very thorough about the process, dare not do no margin.

Jinling and other shipyards have achieved no margin to close View the original post

When the segmented group, the total section is carried in the process, the sub-(total) section is closed, the accuracy is measured, the accuracy is ensured, and then the margin is marked, and then the cutting margin, and then the secondary positioning (generally called reset), and finally the segment reaches the designated group position and the total section reaches the designated carrying position, and tries to ensure the accuracy and line shape View the original post

Each segment has a finished measurement drawing when the drawing is made, which is marked with the rib line or the reference line, the alignment line, etc., the rib inspection line or the reference line plays the role of positioning or measuring its deformation in the segmented assembly process, and when it comes to the segmented group, as long as the distance between the two pairs of the junction line at the large closure of the two segments is in the controllable range, it is basically OK. I don't know much about the specifics, I don't have a deep understanding, I hope you will give me more advice! View the original post

As for what you will say about the situation of a positioning of enterprises in South Korea is not uncommon now, at present, there are several domestic companies to carry out precision management, computer simulation of the segmentation of the carrying, first cut off the margin and only use it once, at present, I know that the domestic enterprises have Shanghai Waigaoqiao and Shanghai Jiangnan Changxing Shipyard can already be in place at one time, not an uncommon thing View the original post

To say, now the domestic shipyard segmented no margin manufacturing rate is not high, but the no margin carrying rate is still quite high, as long as the segmentation accuracy control is done, the slipway dock will be trouble-free, secondary positioning time-consuming, laborious and expensive View the original post

In the group stage, segmented positioning is called one-time positioning. After the completion of the total group, it will be officially docked and carried, and it will be positioned once, which is called secondary positioning. View the original post

I asked the master today, and said that the secondary positioning is actually a waste of docking period, mainly because the accuracy of the front end is not enough, and the deformation of the total section of each segment, when accumulating to the carrying, it adds up to a lot. As a result, even if the cutting allowance is still not docked, the gantry crane is driven away first, and the unqualified segments are processed. Then adjust the gantry crane to carry out secondary positioning.

I heard that Kawasaki and some Korean shipyards have all succeeded at one time, and they don't even need to leave a margin. These are what my master said. Don't know, right?

I hope you will point out and view the original post".

Secondary positioning is a must in our factory.,Cough,No way,The level is low View the original post".

Two people look at each other's position, and generally both sides need to install a positioning application, the kind to prevent getting lost.

For example, Sigui, you can view the location, the movement track within 15 days, suitable for positioning between family and friends, anti-lost, and so on.

Use the instructions in the software.

Hope it helps...

Car positioning, it can be seen from the display in the figure that it is mainly a parking lot display, and the mobile phone positioning display will not be the parking lot to indicate the stay time, what software is not easy to speculate.

Guangxi Tashan automobile equipment **** is not bad.

It must be updated quickly through places with shore-based reporting lines, and there is no signal on the ocean at all by relying on AIS information updates!

Find the Ministry of Defense or the Military Commission and ask them to give you a couple of satellites or ask them to give you the captain's **.

Student notebooks are generally used for design. Game. So the configuration generally has to keep up with the mainstream. But the price must be able to meet the needs of students, and cost performance is the key. HP recommends not buying, the cost performance is very high, but the quality is not very good, this is recognized.

Thank you for adopting.

Of course, it's no problem to play games, but it's definitely a little worse than the 5000 price point.

HP notebooks have become more and more bad in recent years, so I don't recommend it.
