Analyzing the Effect of SMAW on Microstructure and Mechanical Properties in HAZ for Low Carbon Steel

With changing trends observed in various industrial zones, different types of assembly or structure are a major requirement. Consideration of material is also an important aspect for different shape and size for these structures. There are different kinds of joining processes and welding is one such method used in manufacturing process chains, either in terms of material or energy consumption. Each welding method has its own importance and different environmental impacts. Shielded Metal Arc Welding is one of the most traditional arc welding methods that makes use of a consumable electrode covered with a flux and is highly versatile in nature. Most welding methods are performed under high temperature conditions, therefore, HAZ a crucial part of welded region is most vulnerable to sensitization. Properties like brittleness in the HAZ of Low Carbon Steel and its relation with the microstructural changes caused due to heat input have been a focus of our work.
