The effects of YAG laser welding conditions on mechanical properties and pressformability (bendability, stretch-formability and deep drawability) of high-strengthtransformation-induced plasticity-aided dual-phase (TDP) steel were investigated.Tensile tests and press forming tests have been conducted for laser butt welded jointsbetween two pieces of the same steel. The tensile property and press formability wereaffected by the welding speed of 100 to 1100mm/min and the energy of 6 to 9J/pulse.Excellent press formability was obtained with the energy of 6J/pulse and the weldingspeed of 300mm/min. It was concluded that the excellent weldability of the TDP steelcan be ascribed to the weld joint formation.
