Sažetak
Occurring late in the manufacturing stream, the joining process is typically the final step in assembly and plays the major role in ensuring structural performance. Additionally, the emergence of near-net-shape processes to produce sub-components has raised the importance of assembly processes as the next area for increased production efficiency. To solve all the joining needs that require welding, many different processes have been developed along the years. Two of welding technologies can be classified as High Energy Density Welding (HEDW) processes because of their working characteristics. These technologies are Laser Beam Welding (LBW) and Electron Beam Welding (EBW). Both are capable of proving extremely highpower- density weld input levels and making deep weld penetration possible. LBW and EBW are quite similar, differing most notably in their source of power. Laser beam welding employs a highly focused laser beam, while electron beam welding uses an electron beam. LBW and EBW have been developed rapidly and have been successfully used in many industrial applications ; the potential of the HEDW process is continuously being exploited in further industrial sectors. This chapter presents description of the fundamental principle of work of both EBW and LBW. Equipment, process parameters, control of energy, weld formation and typical joint designs are described.
