EFFECTS OF POST WELD HEAT TREATMENT ON

This study is conducted to assess the influence of post weld heat treatment on hardness value. The purpose of this study is to measure and analyse the hardness value before and after post weld heat treatment (PWHT) with three different soaking temperatures and three ASTM A36 carbon steel specimens.
