Title: Detection of welded place in continuous treating process of strip steel and the like
Inventor: TANAKA NOBORU
IPC: C21D9/56
Filed: 1985-07-30
Abstract: PURPOSE:To detect exactly welded place from punched hole, by calculating a distance from a welding machine to a punched hole detector, from the position of a loop car at time point when the loop car is going to normal position after welding and hole punching. CONSTITUTION:For welding a preceding steel sheet coil 1A and the following steel sheet coil 1B, the loop car 2 is moved to the welding machine 7 from a prescribed normal position. During the movement, welding and hole punching are ended and the car 2 begins to move to normal position due to command of the machine 7, and at the time point, the position of the car 2 is detected by a detector 9. Basing on this, distance of coil course path from the machine 7 to the weld punched hole detector 8 is calculated and time when punched hole reaches the detector 8 is calculated from line speed at the time pint by a control part 10. In this way, the hole detected by the detector 8 at the lapse of time from the time when the car 2 begins to move to normal position is determined to be the true weld position.
