Application of flux cored arc welding (fcaw) without pre-heating for heavy structures in ship building fabrication & construction of heavy offshore structural steels
Abstract: In fusion welding processes, the reason often given to explain the need for preheating, controlling the inter pass temperature (in multi-pass welds), and post-weld heat treatment (PWHT) is to reduce the risk of residual stresses and it can be removed by heating weldment in the heat affected zone (HAZ). Cold cracking is a hydrogen embrittlement phenomenon, often referred to as hydrogen induced cracking or HAZ cracking. During the construction and …
