Sensor integration for robotic laser welding processes [PDF]
, 2005 The use of robotic laser welding is increasing among industrial applications, because of its ability to weld objects in three dimensions. Robotic laser welding involves three sub-processes: seam detection and tracking, welding process control, and weld ...

Influence of welding sequence on welding distortions in pipes [PDF]
International Journal of Pressure Vessels and Piping, 2008 This paper presents a three-dimensional thermo-mechanical analysis to investigate the effect of welding sequence on welding deformations in pipe-pipe joints of AISI stainless-steel type. Single-pass TIG welding with V-joint geometry in pipes having a diameter of 274 mm and a thickness of 6.2 mm is studied here.

Advanced Engineering Materials, EarlyView.Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot

Diffusion welding in air [PDF]
, 1974 Solid state welding a butt joint by fusion welding the peripheral surfaces to form a seal is described along with, autogenetically cleaning the faying or mating surfaces of the joint by heating the abutting surfaces to 1,200 C and heating to the ...

Journal of Materials Research and Technology, 2023 Directed energy deposition (DED) process involves complex cyclic reheating and rapid cooling, which probably lead to differences in microstructure and corrosion resistance from the wrought alloys. In the present study, the pitting corrosion resistance of
