Abstract : System models were constructed of mild steel and HY-80 steel plates to approximate plate and stiffener construction in ship fabrication. Flame heating temperature and point of application were varied in the experiments. Welding procedures, water quench rate and flame heating processes were maintained constant. In this study it was shown that flame straightening of HY-80 Steel Structures is less effective in reducing weld distortion, whereas, for mild steel the process is effective. Also, varying the point of heat application has varying effects on the amount of distortion removal. (Author)
