Tensile tests have been conducted for laser butt welded joints obtained from the combination of the same steel. The tensile properties were affected by the welding speed and the pulse energy. The joint penetration was obtained by using the energy of 15.2 J/pulse (mean power: 685 W, pulse frequency: 45Hz, pulse width: 3.8ms) and the welding speed of 250 mm/min. It was concluded that the YAG laser weldability of the 22MnB5 steel was ascribed to the weld joint formation.

内容記述 | The effects of YAG laser welding conditions on mechanical properties of ultrahigh strength 0.23C-0.19Si-1.29Mn-0.013P-0.001S-0.052Al-0.024Ti-0.21Cr-0.003B (mass%) hot-formed (22MnB5) steel were investigated.
