Abstract

PURPOSE: To remove automatically the strain on the steel sheet, by carrying out automatically the travelling and stopping of the travelling machine carrying the heater and cooler and the operation of the above heater and cooler, when the strain generated on the steel sheet owing to the welding is removed by heating and cooling.
CONSTITUTION: The rail 2 is fixed on the steel sheet 1 on which the strain has occurred owing to the welding and the travelling machine 3 is made to travel on this rail 2. The torch 5 and the nozzle 6 for cooling water are equipped to the arm body 4 of the travelling machine 3 and the stopper 59 butting against the limit switch 53 is installed on the rail 2. When the power source is switched on, acetylene gas and oxygen are fed to the torch 5, which is fired then. With the straight advancing movement of the travelling machine 3 and the reciprocating movement of the arm body 4, the torch 5 and the nozzle 6 carry out the movement of the shape of a sine wave and, in this manner, heat and cool the steel sheet 1. In this way, by heating and cooling uniformly the strain part of the steel sheet 1, the strain is removed. The limit switch 53 of the travelling machine 3 butts against the stopper 59, stops the feed of gas and cooling water and, at the same time, stops the movement of the travelling machine 3 and the arm body 4.
