• Resumen

  • A three–dimensional numerical finite element model has been developed to predict the distortion pattern in butt welded specimens produced by welding of thin ferritic steel plates. The sensitivity of distortion to the filler metal used was examined using a conventional weld wire and a low transformation temperature weld wire. The model employed allows the effect of transformation start temperature (Ts) on distortion to be investigated. The results show that the usage of a low transformation temperature weld wire significantly reduces the weld distortion.
