Which cracking risk increases when welding high-carbon steel beams?

💡 Explanation

Hydrogen-induced cold cracking (HICC) increases because hydrogen diffusion occurs in the heat-affected zone. Therefore, residual stress from welding combines with hydrogen embrittlement creating cracks, rather than simple solidification or lamellar tearing under lower-carbon content.
