Paper presented at the The Twenty-fifth International Ocean and Polar Engineering Conference, June 21–26, 2015
Paper Number: ISOPE-I-15-729
... Abstract The advantage of laser welding is that deep penetration with keyhole is obtained due to high density heat input, and heat effect to the metal becomes smaller than arc welding. However it is difficult to analyze the mechanism of keyhole formation and penetration by laser welding...

.... However, due to its thin plate thickness, i.e. about 4~6 mm at most, it is assembled by high power CO 2 laser welding to minimize the welding deformation. Laser is shot on face sheet plate at the joint of the face sheet plate and web plate (I-core). The laser penetrates the face sheet plate and reaches...

... ABSTRACT In order to obtain the pressure vessel of further sound durability and stability under high temperature, high pressure and hydrogenous environment, laser welding application to low alloy 2.25Cr-1Mo steel has been tried in this paper. The mechanical phenomenon of thermal elastoplastic...
