Abstract

PURPOSE:To automate the flush butt welding by impressing the high-frequency voltage on both electrodes of flush butt welding equipment via a contact detector to detect a contact state between metal members to be welded by the variation of the high-frequency voltage or current and controlling properly the initial contact position of both the metal members. CONSTITUTION:At the time of performing the flush butt welding of the end faces of the metal members 1 and 2, a terminal of secondary side winding of a power source transformer for welding is connected to between electrodes 8 and 9 fitted to the respective metal members and a high-frequency power source 14 connected in parallel is connected thereto. Both the metal members 1 and 2 are brought into contact with each other and the high-frequency current is carried from the high-frequency power source 14 and the contact state between both the metal members 1 and 2 by the sudden variation of the voltage and current between both the electrodes 8 and 9 is detected by the contact detector 15 provided in series to its circuit and a cylinder 5 is driven via a servo valve controller 7 and a servo valve 6 by its signal and the metal member 1 is moved on right and left by a pedestal 4 an the initial positioning of both the metal members is carried out properly and a primary side switch 10 of an AC power source 11 is turned on to perform flush butt welding.
