Abstract

PURPOSE: To accurately and easily carry out U-shaped guide bend of welding test piece having a different tensile strength, by pressing the male mold to U-shaped groove of female mold in order that the center of weld zone of the test piece is always positioned at the center of U-shaped formation.
CONSTITUTION: A test piece P of a stainless steel S welded with inconel I, is placed in order that the center of weld zone of a test piece P is positioned at the center of U-shaped groove of a female mold 11 and a bolt 15 is tightened and then, the piece P is put between a press face a of a press pieces 13, 13'. Next, a male mold 12 is pressed on the piece P by operating the fluid cylinder and guide bend is carried out by bending the piece P. At this time, when the center of weld zone of the piece P begins to slip for the inconel I side, press of the piece P is stopped by the mold 12 and a bolt 14 is touched on the upper face of the piece P and then, is tightened. Then, the mold 12 is pressed on the U-shaped groove of the mold 11 and the piece P is bended in U-shaped perfectly.
