Notches are positioned to locate the final crack tip in parent material, weld metal or heat affected zone (HAZ), as defined by the customer. (W 26) (1)

Parent material = Material de origem

When welding the more difficult and thicker materials the flow of plasticised material around the probe becomes an important consideration. (W 549) (2)

Plasticised material = Material plastificado

…The external and accessible internal weld surfaces plus ½inch (13mm) of base material on either side shall be examined. (W 45) (3)

Base material = Material base
