Correction of Butt-welding Induced Distortions by Laser Forming
Welding-induced distortion is an intrinsic phenomenon arising due to the thermally induced strain distributions in the weld and surrounding material. The distortion can be minimized during the pre-process, real-time, or postprocess stages. In the present paper, the laser forming (LF) technology is utilized for the post correction of welding-induced distortion. The out-of-plane distortion can be...
متن کاملCorrection of Butt-Welding induced Distortion by Laser Forming
Welding-induced distortion is an intrinsic problem arising due to the mismatch of thermal expansions in the weld and surrounding material. The distortion can be minimized through the pre-process, in process, or post-process methodology. In the present paper, the laser forming (LF) technology is utilized for the post correction of the welding-induced distortion. Three types of weld paths are app...
متن کاملModeling of input-output Relationships for electron beam butt welding of dissimilar materials using Neural Networks
Electron beam butt welding of stainless steel (SS 304) and electrolytically tough pitched (ETP) copper plates was carried out according to central composite design of experiments. Three input parameters, namely accelerating voltage, beam current and weld speed were considered in the butt welding experiments of dissimilar metals. The weld-bead parameters, such as bead width and depth of penetrat...

متن کاملEffect of welding on impact toughness of butt-joints in a titanium alloy
Impact toughness of a gas tungsten arc welded Ti /6Al /4V alloy butt-joint was evaluated at room temperature using standard Charpy V-notch specimens. The Charpy specimens were prepared with notch roots located either in the parent metal, in the heataffected zone (HAZ), or in the weld metal. Optical metallography and Vickers microhardness test showed that the weld metal has the coarsest grains a...
