High-power lasers are very effective in welding of plates thicker than 10 mm due to the keyhole mode. High-power intensity generates a vapor-filled cavity which provides substantial penetration depth. Due to the narrow and deep weld geometry, there is susceptibility to high hardness and weld defects...

For many years, the oil and gas industry has utilized superduplex stainless steels due to their high strength and excellent corrosion resistance. Wire arc additive manufacturing (WAAM) was used with superduplex filler wire to create walls with different heat input. Due to the multiple heating and co...

Laser beam welding (LBW) and laser-arc hybrid welding (LAHW) are attractive joining methods of medium thickness (10-20 mm) plates in a single pass welding technique. Both utilize high energy process in order to achieve high penetration depth and high welding speeds offering substantial increase in p...
