This paper reports the results of V-Notch Charpy Impact tests performed on one-pass weld specimens and transition temperatures obtained. The results were as follows : (i) The transition temperatures of one-pass weld specimens were always above the room temperature. (ii) The Charpy Impact values at temperatures below room temperature were low irrespective of the coating types hnd steel plates, giving the lower values than those of base metals (mild steel plates) (iii) The Charpy Impact values of one-pass weld specimens could be improved by multipass welding and gave much higher values than those of base metals.
