Q2Domain Verified
Considering the principles of heat input control discussed in "The Complete Foundational Welding Course 2026," what is the primary metallurgical consequence of excessive heat input when welding medium-carbon steels, leading to reduced toughness and increased susceptibility to hydrogen-induced cracking?
Increased ductility of the weld metal
Formation of martensitic structures in the HAZ
Grain refinement in the heat-affected zone (HAZ)
Reduced residual stresses
Q3Domain Verified
