WebMar 19, 2024 · Weld Defects: Weld defects are one of the major damage cause for break down of boiler. These type of failures often happens while boilers are in service and lead to break down of boiler/steam generator. The basic type of weld defects are lack of fusion, lack of penetration, slag, undercut, porosity, excess penetration.

What is creep? Creep may be defined as a time-dependent deformation at elevated temperature and constant stress. It follows, then, that a failure from such a condition is referred to as a creep failure or, occasionally, a stress rupture. The temperature at which creep begins depends on the alloy composition.
