Abstract

PURPOSE: To enable to accurately and safely test the quality in a short time, by providing detachable pushing projection on the upper face of lower ram of flash trimmer and forming expanded part pressing the weld zone of strip.
CONSTITUTION: After the strip 7 is put between the upper and lower clamp beam 2,3, cutting processing from the top to the bottom of burr in the strip width direction, is carried out in order of the cutting blade 10dW10a pulling the upper and lower ram 5,6 by the truck 8 after putting the strip 7 between the clamp beam 2,3. Next, the ram 6,7 are pushed back to the original position by the truck 8 pulling up the upper clamp beam upward and the pushing projection 11 is provided with bottomed perforation of the lower ram. Then, the projection 11 is reached the weld zone test position of the strip 7 pulling the ram 5,6 and after that, expanded part is formed by pushing down the beam 2. Next, existence of crack or abnormal deformation is examined by observing expanded part with eyes.
