Not all cracks are defects.
In high-hardness overlays, check cracking is a normal and expected stress-relief mechanism. These small cracks typically form perpendicular to the weld bead as it cools, helping release internal stress caused by shrinkage.
However, cross cracking or cracks extending into the base metal may indicate improper welding procedures, incompatible materials or excessive stress.
Understanding the difference is essential for achieving a successful, long-lasting hardfacing application.
