Abstract
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 degrees 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 oscillating beam joints have been attributed to their narrow weldment region with homogenous microstructure and 6-ferrites of lathy morphology.
