Thermal Soil Cracking (Soil Dry-Out): Heat from cables can cause moisture to migrate away from the soil, leading to "cracks" or dry spots that significantly increase thermal resistance. This reduces the cable's current-carrying capacity (ampacity).
For engineers: specify filler metals with adequate manganese or ferrite, and never assume the capping pass is "just cosmetic." It is the armor of your weld, and a crack in the armor is a failure waiting to happen. cymcap hot crack
, which is a common cause of unexpected localized hot spots. Validation Standards: The software is strictly aligned with IEC 60287 and IEC 60853 Thermal Soil Cracking (Soil Dry-Out): Heat from cables
A Cymcap hot crack is, in essence, a high-temperature fissure that appears in the capping pass (the top layer of weld metal) before the assembly has cooled to ambient temperature. Unlike cold cracks (hydrogen-induced), which appear hours or days later, hot cracks manifest almost immediately—often with an audible "pop" or visible collapse of the weld bead. If left unaddressed, these cracks lead to structural fatigue, leakage in pressure systems, and ultimately, complete joint failure. , which is a common cause of unexpected localized hot spots
