Description
Kaixuan Sang and co-authors study laser welding of a high-strength car steel in 2024. The steel, a boron grade for hot-formed parts, came in plates two, three, and four millimeters thick. How thickness changes the weld's inner structure and strength matters for factory use.
Thicker plates gave weaker joints, falling from ninety-six to eighty-eight percent of the base metal's strength. The heat-affected zone beside each weld was the softest part. Grains in the weld grew coarser with thickness, changing from fine needles to larger islands, and defect density dropped. All three joints still cleared eighty-five percent of base strength, a good sign for industry.
