Which risk increases after poor welding practices on high-strength steel bridge support beams?

💡 Explanation

After poor welding, hydrogen-induced cracking occurs because atomic hydrogen diffuses into the weld metal and heat-affected zone, embrittling the steel and causing cracks. Therefore, hydrogen-induced cracking results, rather than galvanic corrosion, erosion, or buckling, which arise from different material pairings, environmental conditions, and structural deficiencies, respectively.
