Welding wire for aluminum-silicon pre-coated steel plate laser welding, aluminum-silicon pre-coated steel plate laser tailor-welded component and production method of aluminum-silicon pre-coated steel plate laser tailor-welded component

The invention discloses a welding wire for welding an aluminum-silicon pre-plated steel plate, an aluminum-silicon pre-plated steel plate tailored blank laser welding component and a production method of the aluminum-silicon pre-plated steel plate tailored blank laser welding component, and the welding wire comprises the following components in percentage by weight: 0.10 to 0.22 percent of C, 0.20 to 0.50 percent of Si, 2.0 to 3.5 percent of Mn, 3.0 to 7.0 percent of Ni, 2.0 to 3.0 percent of Cr, 0.020 to 0.030 percent of Nb and the balance of Fe and inevitable impurities. According to the welding wire for laser welding of the aluminum-silicon pre-plated steel plate, tailored blank laser welding is carried out on the aluminum-silicon pre-plated steel plate by adopting the welding wire for laser welding of the aluminum-silicon pre-plated steel plate and a laser wire filling welding method, and then hot forming is carried out on a blank obtained after tailored blank welding is completed, so that a joint of an o
