STEEL BARS WELDING JOINT FROM OF CONSTRUCTION WORK OF EXAMINATION : A proposal of execution single V groove method of the site weld ioint

Abstract

In this report, I did a survey of transition of carbon equivalent in welding joint of a reinforcing rod. As a result it became clear that heat-affected crack occurred by decrease of carbon equivalent as execution a large amount progressed. Therefore, in the point of the site weld management, it is thought that the defect can correct it by making much of single V groove.
