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. 矫平铣边：通过压砧机使原来卷曲的钢板平整,再通过铣边机对钢板两边缘进行双面铣削,使之达到要求的板宽、板边平行度和坡口形状。

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：在生产线上将钢板沿外沿螺旋卷曲成管状。

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

4. 对焊切割：采用的双面埋弧焊技术进行预焊接，内焊接，外焊接。将焊接成型的方管使用等离子尺切割成规范长度。

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. 目视检查：由专业技术人员对一些基本的参数进行检查。

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

6. 超声波探伤：对内外焊缝及焊缝两侧母材进行100%的检查。

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射线探伤:对内外焊缝进行100%的X射线工业电视检查,采用图象处理系统以保证探伤的灵敏度。

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. 打压试验:在水压试验机上对方管进行逐根检验以保证方管达到标准要求的试验压力。

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. 倒棱平头：将检验合格后的方管进行管端加工,达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. 后检查：再次进行超声波和X射线探伤以及进行管端磁粉检验,检查是否存在焊接问题及管端缺陷。

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. 涂油打标：合格后的方管进行涂油以防腐蚀，并根据用户要求进行打标。

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