Abstract
This paper presents the experimental results of the impact toughness and hardness of welds deposited on H13 hot work tool steel. To obtain the optimum combination of high hardness and high toughness, multipass gas tungsten arc welding was used to melt four different commercially available filler materials suitable for repair welding of HWTS. Special geometry of the welding sample is presented in this work. The focus is also on the technique of the preparation of the V-shaped notch in order to precisely evaluate the impact toughness. Two different preheating temperatures and two different post weld heat treatments were applied to the samples in order to obtain the effect of heat treatment on the impact toughness and hardness. Data show that weld deposited with filler material C on the base of the hot work tool steel and alloyed with vanadium exhibits high impact toughness in combination with high hardness in the as-welded condition and also after tempering.
