摘要： PURPOSE:To improve forming and butting and even from a large diameter thin tube, to prepare a true circle without crop in forming an electric welded tube by semi-cage roll system by restraining the edge of steel plate using a V-roll in the upper stream side of the first fin pass roll. CONSTITUTION:A steel plate S is bent to U-shape by a break down roll 2 and an inner cage roll 4, and then bent gradually to true circle by combination of a V-roll 1 that presses the edge (a) of the steel plate and an outer roll 5, and enters the first fin pass roll 3. The welded tube is improved by this forming and butting process. By restriction of the V-roll, the generation of crop is prevented and a good true circle tube can be obtained even in the case of a large diameter thin tube.

摘要： PURPOSE: To obtain the bead of high quality at the seam terminal by selecting adequately the welding current, welding voltage and welding speed at the seam terminal welding time.
CONSTITUTION: The stationary part is welded under steady welding conditions, for instance, of the current I
0 : 500A, voltage: V 25V, speed S
0 : 4m/min in the seam welding of UOE steel pipe. When approaching to the terminal part it is transferred to the terminal welding conditions of causing no arc blow of, for instance, current I
1 : 170A, voltage V
1 : 17V and speed S
1 : 1 m/min at the time T of for instance 1W1.5 sec by an integrating circuit. In case of performing the high speed welding of MIG, MAG, TIG, etc. this method can be applied for every field which needs the control of bend shapes.

摘要： PURPOSE:To improve cutting efficiency by providing an edge miller with side rollers at the upper stream sides and by cutting a steel sheet to a specified width by the edge miller after rolling the edges of the steel sheet in the cross direction. CONSTITUTION:Side rollers 3 for rolling a steel sheet S to a specified width is provided at the upper stream of an edge miller 1. The steel sheet S is rolled by these side rollers 3 to a specified width in the cross direction, and then the edges of the steel sheet are cut by the edge miller 1. In the process of rolling to a specified width, the steel sheet is rolled to the specified width +2to(to: dimension error) and after that, the edge miller performs cutting of the edge of to per one side. By performing the rolling to the specified width before cutting, the cutting amount can be lessened and the cutting efficiency can be improved.
摘要翻译：目的：为了提高切割效率，通过在边缘铣刀的上游侧提供侧辊，并且在横向滚动钢板的边缘之后，通过边缘铣刀将钢板切割成特定的宽度来提高切割效率。构成：在边缘铣刀1的上游设置有用于将钢板S轧制到规定宽度的侧辊3.钢板S由这些侧辊3在横向上被轧制成规定的宽度，然后钢板的边缘由边缘铣刀1切割。在轧制到特定宽度的过程中，将钢板轧制到指定的宽度+ 2到（尺寸误差），然后边磨机进行切割每边的边缘。通过在切断前进行规定的宽度的轧制，可以减少切削量，提高切削效率。
