Now-a-days, electron beam welding is extensively used in piping and pressure vessel of nuclear industry because its advantages with respect to no use filler material, lower distortion residual stresses. Therefore, the paper aims evaluate weld pool size, deformation stresses 13.5 mm thick pipe outer diameter 170mm made austenitic stainless steel (SA312 Type 304L) a butt joint configuration prepared by Electron Beam Welding (EBW). Pipe back plate has been EBW heat input 825 700 J/mm qualified...
Butt welding of austenitic stainless steel 304 plates was carried out using an electron beam. Experiments were conducted for various combinations input process parameters determined according to central composite design. Three parameters, namely accelerating voltage, beam current, and speed considered during the experiments. The weld-bead bead width its depth penetration, weld strength in terms yield ultimate tensile strength, measured as responses process. Input–output modelling this...
Electron beam butt welding of stainless steel (SS 304) and electrolytically tough pitched (ETP) copper plates was carried out according to central composite design experiments. Three input parameters, namely accelerating voltage, current weld speed were considered in the experiments dissimilar metals. The weld-bead such as bead width depth penetration, strength terms yield ultimate tensile measured responses process. Input-output relationships established forward direction using regression...
Abstract In the present study, electron beam welding bead-on-plate of electrolytic pitched copper (ETP-Cu) plate was carried out to study behavior different defects formed in weld by varying oscillation amplitudes. The like spattering, spiking and porosity were considered this study. Spattering phenomena determined with visual inspection image analysis software, respectively. Porosity measurement conducted X-ray tomography. found decrease amplitude up optimized value then, it showed an...
Abstract High energy density welding processes like laser and electron beam are capable of dissimilar plates with much ease due to high power low heat input in spite the varying thermos-physical properties used alloys. The present work is aimed check feasibility joint prepared SS 316L Inconel 718 plates. experiments designed study effect speed on mechanical metallurgical behavior joints without any offset line. formation laves phases confirmed by dispersive spectroscopy (EDS) X-ray...
Plasma melting technology can be used to meet the scrap recycle needs of reactive metals, superalloys and refractory materials such as titanium, zirconium uranium alloys. Fabrication involving these share common problem generating a large amount where both low high density inclusions become highly prevalent. for re-melting, refining production premium grade metal ingot. 450kW multi-torch plasma furnace is developed commissioned by Laser & Technology Division re-melting metals scraps under...
