Abstract
A tool peels apart a sample weld between a top sheet and a bottom sheet of metal while the bottom sheet is held in a vise. The tool includes a wheel having a peripheral rim surface. A handle is attached to the wheel so that rotating the handle rotates the wheel. A clamping mechanism is mounted on the wheel and moves between an open position spaced from the peripheral rim surface and a closed position in which the clamping mechanism clamps the top sheet to the peripheral rim surface so that rotation of the wheel by the handle will progressively wrap the top sheet about the peripheral rim of the wheel and thereby forcibly peel the top sheet away from the bottom sheet to pull apart the weld between the top and bottom sheets.
