Abstract

Measuring the hardness in the heat affected zone of welds is often considered as a convenient means to obtain easily information relative to the weldability of structural steels and or to the behaviour of weldments in service. A general association developed over the years between excessive harness levels in the weld zone and difficulties that were encountered during welding with cold cracking and/or during service with weldment performances.

Abstract

The classification of steels based upon the Charpy V transition temperature is now widely accepted and included in ISO standards. The genesis of currcnt practice for the selection of steels in welded constructions based on the Charpy V transition temperature was the systematic analysis of brittle fractures of all welded structures built during World War II and in particular of ships of the U.S. Navy.
