Full penetration weld

Description:Depending on the penetration, two kinds of butt welds are defined: However, if significant and consistent root penetration can be achieved, which significantly increases the effective throat depth, then the fillet leg size can be reduced without sacrificing weld strength see example in Figure 7. Weld strength is not determined by the level of penetration into the base plates. However, if appropriate procedure trials have been made, the throat thickness can be taken as equal to the preparation. Are these statements accurate? In other cases, a thin root pass is made in an open root joint e. As long as you have achieved complete fusion between the filler metal and the base plates and when appropriate, the steel backing bar , you have successfully joined the metal together into one homogenous piece.
