1、對原材料進行各種的檢查。原材料一般是指帶鋼卷，焊絲，焊劑等。在投入前都要經過嚴格的理化檢驗，才能保證質量。

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、帶鋼頭尾對接，采用單絲或雙絲埋弧焊接，在卷成鋼管后采用自動埋弧焊補焊。

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、 濟鋼一級代理商進行工藝處理。在成型前，所需的鋼材經過矯平、剪邊、刨邊，表面清理輸送和予彎邊處理。

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、采用電接點壓力表控制輸送機兩邊壓下油缸的壓力，確保了帶鋼的平穩輸送。

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、采用外控或內控輥式成型。

5. Using external or internal control roll forming.

6、采用焊縫間隙控制裝置來保證焊縫間隙滿足焊接要求，管徑，錯邊量和焊縫間隙都得到嚴格的控制。

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、內焊和外焊均采用電焊機進行單絲或雙絲埋弧焊接，從而獲得穩定的焊接規范。

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、焊完的焊縫均經過在線連續超聲波自動傷儀檢查，保證了100％的螺旋鋼管的無損檢測覆蓋率。若有缺陷，自動報警并噴涂標記，生產工人依此隨時調整工藝參數，及時消除缺陷。

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、采用空氣等離子切割機將鋼管切成單根。

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