In general, microcracking is less of a problem in metals that show good elongation in tensile tests. If you work with certified materials, be sure the elongation measurements of the lot meet or exceed the elongation specification for the type/grade of material.

Unlike hot cracking, which occurs right away, cold cracking can occur in the weld metal, hours or even days after welding. A single visual part inspection made directly after a weld may not be adequate to detect cold cracking.

The most damaging form of cold cracking is hydrogen embrittlement. This occurs when hydrogen is absorbed into the metal. Hydrogen embrittlement is usually associated with dust and dirt that has accumulated on the weld surface or from using a damp electrode.

This embrittlement is extremely harmful in alloy steels and it often happens in carbon steels. Structures suffering from hydrogen embrittlement lose their toughness and often fail. If you suspect hydrogen embrittlement, especially if porosity is present in alloy steel, invest in a metallographic examination of a weld sample.
