Control of microstructures and properties in steel arc welds
Lars-Erik Svensson
Routledge, 2017
Welding is a fascinating subject, involving knowledge from many disci plines such as physics, chemistry, metallurgy, electronics, and mechanical engineering. However, welding is still in many respects regarded as a crafts manship, with the welder having a large influence on the final properties of the welded joint. Thus, the possibility of predicting and controlling the properties of a welded joint is limited.
The intention of this book is to show that the properties of a weld in steel can be predicted and controlled through control of the microstructures that appear. There has been a rapid development in this field during the 1980s, mainly through the development of models for the microstructure of steels subjected to welding. These models are quantitative to a certain degree, with calculations carried out on mainframe computers or PCs. However, it must be realized that these models are still far from mature and certainly much more development is needed to say that we can completely control the microstruc ture and properties of a welded joint.

The iron powder not only melts in the heat of the arc to increase deposition rate but also enables the electrode to carry a higher welding current than a 'standard' electrode. The iron ..
