Chapter 2: "New approaches to the Friction Stir Welding of aluminum alloys" written by Marcello Cabibbo, Archimede Forcellese, and Michela Simoncini. The main contribution of this chapter is the presentation of two new methods to weld aluminum alloys sheets by using

Chapter 3: "A mesh-free solid mechanics approach for simulating the friction stir welding process" written by K. Fraser, L. St-Georges, and L. I. Kiss. The main contribution of this chapter is the introduction of a new approach to simulate FSW by smoothed particle hydro‐ dynamics (SPH). This approach can determine elastic and plastic deformation, residual

Chapter 4: "Gas Tungsten Arc Welding with Synchronized Magnetic Oscillation" written by Thiago Resende Larquer and Ruham Pablo Reis. This chapter describes a method of controlling arc motion using the magnetic oscillation method of GTAW. The good coordination of magnetic oscillation and the welding process can influence the delivery of arc energy to the

Chapter 5: "A Comprehensive mode of the transport phenomena in Gas Metal Arc Welding" written by J. Hu, Z.H. Rao, and H.L. Tsai. This chapter explains the development of a com‐ prehensive two-dimensional GMAW model, which considers the effect of arc plasma, electrode condition, droplet formation, detachment transfer, impingement onto the workpiece and the weld pool, and weld formation. This model uses volume of fluid approaches to track the free surface, which can eliminate the requirement of boundary condition at the interface. Chapter 6: "The analysis of temporary temperature field and phase transformation in one-side butt welded of steels flats" written by Jerzy Winczek. This chapter describes model approaches for temperature field and phase transformation analysis of butt welding. This model is verified by metallographic observation of the butt weld workpiece, which was welded using an arc

Chapter 7: "Laser and Hybrid laser-arc welding" written by G.A. Turichin. This chapter explains the technology of laser and hybrid laser-arc welding. It discusses the uniqueness of laser and hybrid laser-arc welding on metals and its potential application in the industry.

Chapter 8: "Current issues and problems in the joining of ceramic to metal" written by Uday M.B., Alias Mohd Noor, and Srithar Rajoo. This chapter describes the challenges of joining between ceramics and metals. These two metals have significantly different properties, so joining of these materials is difficult. This chapter explains various studies that have been

Chapter 9: "Diffusion Bonding: Influence of Process Parameters and Material Microstructure" written by Thomas Gietzelt, Volker Toth, and Andreas Huell. This chapter deals with the technology of diffusion for welding application. The parameters that influence mechanical properties and the microstructure, as well as those involved in diffusion welding, are dis‐
