Elsevier Hybrid Laser Arc Welding (Series in Welding and Other Joining Technologies)

Hybrid laser-arc welding (HLAW) is a combination of laser welding with arc welding. It overcomes some of the shortfalls of both processes. Hybrid laser-arc welding combines deep weld penetration of laser welding with good gap tolerance of gas metal arc welding (GMAW). HLAW can also enhance the metallurgical stability of a finished component, giving welds that are stronger and less brittle. This important book provides a comprehensive account of hybrid laser-arc welding including technological aspects, hybrid welding of metals, applications and future trends. Key Features: reviews arc and laser welding including both advantages and disadvantages of the hybrid laser-arc approach; explores the characteristics of the process including the properties of joints produced by hybrid laser-arc welding and ways of assessing weld quality; examines applications of the process including magnesium alloys, aluminium and steel with specific focus on applications in the shipbuilding and automotive industries.
