Thank # Wenmeng for pursuing excellence, Zhai Lijuan Shared material.
10) When the fixture is used for assembly, it shall not be knocked down with a hammer when removing the fixture, it shall be cut off with gas cutting, the base metal shall not be damaged, and it shall be leveled with a grinding wheel.
of the members, and permanently marked as the basis for the inspection, pre inspection and acceptance of steel members.
Solar power stations, solar water heaters, electric vehicles and energy storage power stations are all based on mass production of batteries, and solar cell production is the demand side of purification projects.
2) The assembly sequence table shall be prepared before assembly.
4) When arranging the assembly mould, its positioning must consider the pre release welding shrinkage and the allowance of flush machining.
You can enter if you abide by the rules 》 (open the link to view the details.) For more purification materials, please refer to 20210927 for more than 60 purification materials and 9.9 for 30 purification materials 、 “Video, audio, articles, all the purification you want is here” Whether it is “like the author” or forwarding, or even opening the ads automatically added in and after the text, it can add a “Shandong big steamed bread”! ********************************************************************..
6) The splicing of plates and profiles shall be carried out before assembly.
Therefore, from today on, we will share the construction organization design of solar cell production projects.
8) Concealed parts of components shall be painted in advance.
(3) assembly and splicing ① assembly principle 1) the assembly must be carried out in accordance with the provisions of the process flow.
11) The control line required for the installation of steel members shall be marked after assembly, indicating the center line, elevation control line, positioning line, etc.

7) For the parts required to be polished and tightened, more than 75% of the area of the top tight fitting surface shall be closely pasted, Check with a 0.3mm feeler gauge, the insertion area is less than 25%, and the edge clearance is less than 0.8mm.
5) Before assembly, the connecting contact surface of parts and components and the rust, burr, dirt, ice and snow within 30-50mm along each side of the weld edge shall be cleaned.
3) In case of concealed welds, welding must be carried out first, and the next process can be carried out only after passing the inspection.
The assembly sequence shall be determined according to the structural form, welding method, welding sequence and other factors.
The assembly of components shall be carried out after component assembly, welding and correction, so as to reduce the residual stress of components.
The assembly shall be carried out in strict accordance with the sequence table.
9) The assembled components shall be marked immediately at the obvious position of the components, indicating the drawing number, part number and quantity.
