Which safety concern arises when welding high-strength steel beams experiencing high tensile load?

💡 Explanation

When welding high-strength steel under high tensile load, hydrogen-induced cracking occurs because diffusible hydrogen within the weld metal embrittles the heat-affected zone due to applied stress. Therefore hydrogen cracking is primary concern, rather than tearing, low fatigue resistance, or distortion problems less specific to high-strength tensile situations.
