1、对原材料进行各种的检查。原材料一般是指带钢卷，焊丝，焊剂等。在投入前都要经过严格的理化检验，才能保证质量。

1. A variety of inspection of raw materials. Raw materials usually refer to strip, wire, flux and so on. The quality can be guaranteed by strict physical and chemical inspection before the input.

2、带钢头尾对接，采用单丝或双丝埋弧焊接，在卷成钢管后采用自动埋弧焊补焊。

2. The head and tail of the strip is butted with single wire or double wire, and the automatic submerged arc welding is used after the steel pipe is rolled into the steel pipe.

3、 济钢一级代理商进行工艺处理。在成型前，所需的钢材经过矫平、剪边、刨边，表面清理输送和予弯边处理。

3, the first level agent of Jigang to process the process. Before the molding, the required steel is leveled, trimming and flanging, and the surface is cleaned and conveyed and treated by the curved edge.

4、采用电接点压力表控制输送机两边压下油缸的压力，确保了带钢的平稳输送。

4, using the electric contact pressure gauge to control the pressure of the cylinder on both sides of the conveyor to ensure the smooth transportation of the strip.

5、采用外控或内控辊式成型。

5. Using external or internal control roll forming.

6、采用焊缝间隙控制装置来保证焊缝间隙满足焊接要求，管径，错边量和焊缝间隙都得到严格的控制。

6, the weld gap control device is used to guarantee the weld gap to meet the welding requirements, and the pipe diameter, the error margin and the weld gap are strictly controlled.

7、内焊和外焊均采用电焊机进行单丝或双丝埋弧焊接，从而获得稳定的焊接规范。

7, both internal and external welding are used for single wire or double wire submerged arc welding by electric welding machine, so as to obtain a stable welding specification.

8、焊完的焊缝均经过在线连续超声波自动伤仪检查，保证了100％的螺旋钢管的无损检测覆盖率。若有缺陷，自动报警并喷涂标记，生产工人依此随时调整工艺参数，及时消除缺陷。

8. The welding seam is checked by the on-line continuous ultrasonic automatic injury instrument, which ensures the coverage rate of the nondestructive testing of 100% spiral steel tubes. If there are defects, automatic alarm and spray marking, the production workers at any time adjusting the process parameters, in time to eliminate defects.

9、采用空气等离子切割机将钢管切成单根。

9, the air plasma cutting machine is used to cut the steel pipe into a single root.
