Preventing Delayed Cracks in Ship Welds. Part II.

Abstract

The report discusses the causes of delayed cracking in ship steel welds and presents the necessary steps necessary to prevent delayed cracking. Three factors, acting together, are responsible for the formation of delayed cracks: hydrogen dissolved in the weld, a hard microstructure in the weld or heat-affected zone, and high stresses within the weld joint. Each step that is taken to prevent delayed cracks has the purpose of eliminating or significantly reducing at least one of these factors.
