What testing is dynamic test in which the weld is broken by a single blow?

Dynamic testing in which a weld is broken by a single blow is known as "impact testing." This method evaluates the toughness and ductility of the weld under sudden stress or impact. Typically, a specimen is subjected to a high-energy impact to assess its ability to withstand rapid loading conditions, which is crucial for ensuring the integrity of the weld in service. Common standards for impact testing include the Charpy and Izod tests.
