Abstract

PURPOSE: To produce a welded zone of thin long-sized steel material with an ideal shape at a high accuracy by preventing distortion due to heating in welding with the internal and external areas of the work fixed firmly by a base, slider, clamper or the like.
CONSTITUTION: A base 1 is provided with a sliding guide groove for a core metal 2 on which a slider 3 having a tapered surface is successively fixed. In this manner, with the movement of the core metal 2, a holder 4 is moved toward work 6 in a wedge way through the slider 3. The holder is constructed integral with a chill strip 7 having a cooling pipe 16 and a welding seal gas pipe 17. The holder 4 has a return mechanism comprising a pin 8, a spring 9 and a washer 10. The base 1 is provided with a receiving plate 11 of the holder and a guide roller 13 for letting the work move in and out. The outside of the wowrk is fixed with a clampers 14 and 15 employing a cylinder 13. This mechanism ensures the fixing of the work 6 and the prevention of distortion in a accurate manner.
