Defects / Imperfections in Welds - Reheat Cracking - TWI
Causes Best Practice in Prevention Steel Choice Welding Procedure and Technique The principal cause is that when heat treating susceptible steels, the grain interior becomes strengthened by carbide precipitation, forcing the relaxation of residual stresses by creep deformation at the grain boundaries. The presence of impurities which segregate to the grain boundaries and promote … See more on twi-global Go to top 7 Causes of Quench Cracking in Steel Production MachiningFailures of steel parts in service or production occur infrequently. However, when steel parts fail, the consequences are dire. Here are seven ways that steel can fail as a result of quench cracking from heat treatment.. Overheating during the austenitizing portion of the heat treatment cycle can coarsen normally fine-grained steels. Coarse-grained steels increase hardening depth and are …sp.info Failure Analysis of Heat Treated Steel Components

By heating the material after welding, it is possible to diffuse hydrogen from the welded area, thus preventing HIC. This process is known as post heating and should begin immediately after the weld is completed.
