Manufacturers often face a dilemma: whether to use conventional steel that is easily joined by traditional welding methods, or use lighter, high-strength steel that reduces weight and adds durability, but can be challenging to weld.

Now scientists in the Oak Ridge National Laboratory (ORNL) Materials Science and Technology Division (MSTD) have collaborated with JFE Steel Corporation on using ORNL’s friction stir spot welding (FSSW) technology to join overlapping sheets of JFE’s advanced high-strength ste
