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 …

Exploring the Synergistic Effects of Heavy Metal contaminants on Aquatic Organisms
Abstract: Human activities have a profound effect on aquatic habitats by altering water and sediment quality, which in turn impacts resident organisms. These changes are primarily caused by pollutants from agricultural, industrial, and health-related sources. Industrial effluents, often containing hazardous heavy metals such as chromium, manganese, and lead, are a major source of environmental toxicity. The discharge of these pollutants makes water unsafe for drinking, irrigation, and industrial uses, necessitating effective …
