Charpy impact test (V gap) : the specified height of pendulum of the one-time blow to V notched specimens in beam state, test specimen is broken by the impactabsorbingenergy.
In welding test of TCS stainless steel, it was found that impactabsorbingenergy of heat-affected zone (HAZ) near bond line in welded joint was low. The reason is coarse grain in HAZ.
