Change of mechanical properties in substrate during rewelding deposit

Popis výsledku v původním jazyce

A study was carried out to examine the influence of rewelding deposit of structural low carbon steel and also the changes which occur in heat affected zone and subcritical zone during rewelding. Optical metallography, microhardness Vickers method and Charpy impact test were employed to analyze these differences. The results show that rewelding deposit increased the heat affected zone and fine coarse grain HAZ and also has influence on impact toughness of substrate and their microhardness. Again, it wasfound that rewelding increased the fine coarse grain HAZ. This effect resulted in increasing impact toughness in the HAZ. However, submicroscopic change in substrate ferrite showed decreasing impact toughness.
