Title: Production of electric welded pipe
Inventor: HAYASHI TOMOTAKA
IPC: B23K13/01
Filed: 1988-12-14
Abstract: PURPOSE:To prevent the generation of welding defects by measuring and calculating the temp. difference in respectively heated both-side edges on the inner and outer sides of an open pipe and correcting the quantity of heat input based on the relation between the previously determined temp. difference and the adequate quantity of heat input. CONSTITUTION:The open pipe 1 is formed into a cylindrical shape, the both-side edges of which face each other, by passing a band-shaped metallic sheet through forming rolls. The open pipe is passed in a high-frequency current coil r disposed on the outer periphery to heat and melt the both-side edges and the edges are butt-welded by squeezing rolls 3 by which the electric welded pipe 2 is formed. Lenses a, 6a are installed to the prescribed positions on the outside and in the inside of the pipe 1 and are connected respectively to pattern thermometers 7, 8 via optical fibers 5, 6. The respective thermometers determine the temp. difference between the inside and outside surfaces of the both-side edges and input the same to an arithmetic unit 9. The correction quantity DELTAP of heat input is calculated in accordance with the prescribed equation in the arithmetic unit and is inputted to a weld heat input control device 10. The control device 10 outputs the control signal corresponding to DELTAP to a welding machine 11 and controls the input voltage (electric power) of the coil 4. The generation rate of the weld defects is lowered in this way even if the difference in the wall thickness exists.
