Quality Control for Construction and Installation Acceptance of Steel Bar Truss Floor Support Plate 1 Uncoiling plate detection: After uncoiling the steel plate and entering the production line, the entire plate is first subjected to ultrasonic inspection.

2. 矯平銑邊：通過壓砧機使原來卷曲的鋼板平整,再通過銑邊機對鋼板兩邊緣進行雙面銑削,使之達到要求的板寬、板邊平行度和坡口形狀。

2. Leveling and milling of edges: The originally curled steel plate is flattened by an anvil press, and then the two edges of the steel plate are double-sided milled by an edge milling machine to meet the required plate width, edge parallelism, and groove shape.

3. 剪切成型：在生產線上將鋼板沿外沿螺旋卷曲成管狀。

3. Shear forming: On the production line, the steel plate is spirally coiled along the outer edge into a tube shape.

4. 對焊切割：采用的雙面埋弧焊技術進行預焊接，內焊接，外焊接。將焊接成型的方管使用等離子尺切割成規范長度。

4. Butt welding and cutting: Advanced double-sided submerged arc welding technology is used for pre welding, internal welding, and external welding. Cut the welded square tube into standard lengths using a plasma ruler.

5. 目視檢查：由專業技術人員對一些基本的參數進行檢查。

5. Visual inspection: Professional technical personnel inspect some basic parameters.

6. 超聲波探傷：對內外焊縫及焊縫兩側母材進行100%的檢查。

6. Ultrasonic testing: Conduct a 100% inspection of the internal and external welds and the base metal on both sides of the weld.

7. X射線探傷:對內外焊縫進行100%的X射線工業電視檢查,采用圖象處理系統以保證探傷的靈敏度。

7. X-ray inspection: Conduct 100% X-ray industrial television inspection of internal and external welds, using an image processing system to ensure the sensitivity of the inspection.

8. 打壓試驗:在水壓試驗機上對方管進行逐根檢驗以保證方管達到標準要求的試驗壓力。

8. Pressure test: Conduct a piece by piece inspection on the square tube on the hydraulic testing machine to ensure that the square tube meets the standard test pressure requirements.

9. 倒棱平頭：將檢驗合格后的方管進行管端加工,達到要求的管端坡口尺寸

9. Chamfering and flat head: Process the qualified square tube at the pipe end to meet the required pipe end groove size

10. 后檢查：再次進行超聲波和X射線探傷以及進行管端磁粉檢驗,檢查是否存在焊接問題及管端缺陷。

10. Final inspection: Conduct ultrasonic and X-ray inspection again, as well as magnetic particle inspection of the pipe end, to check for welding problems and pipe end defects.

11. 涂油打標：合格后的方管進行涂油以防腐蝕，并根據用戶要求進行打標。

11. Painting and marking: Qualified square pipes should be coated with oil to prevent corrosion and marked according to user requirements.
