TWI Industrial Member Report Summary 796/2004
C H J Gerritsen
Background
With CO 2 laser and hybrid CO2 laser MIG/MAG welding now proven for shipbuilding applications, the interest is moving on to hybrid Nd:YAG MIG/MAG welding because of the benefits the flexible fibre beam delivery can give in terms of the ease of welding head manipulation. The European Union sponsored project ShipYAG was set up to do just that. This report covers the development of hybrid Nd:YAG laser MAG welding procedures for T joints for shipbuilding applications, as part of the ShipYAG project.
Objective
To develop welding procedures for hybrid Nd:YAG laser MAG welding of T joints in 4 to 5mm and in 10 to 12mm C-Mn shipbuilding steels.
