Effect of Beam Oscillation on Creep Properties of Electron Beam Welded AISI 316L Stainless Steel

Butt-joints of AISI-316L stainless steel sheets were produced by electron beam welding process using both static and oscillating beams. The creep properties of the joints were investigated by conducting open-atmosphere creep rupture tests at 650 and 700 °C under an applied stress of 200 MPa. Such tests demonstrated higher creep-rupture life (more than twice) for oscillating beam joints than the static beam joint. Better creep properties for...
