Welding method of high-strength steel plate and ship

The invention relates to the technical field of ship construction, and discloses a welding method for a high-strength steel plate and a ship. The welding method comprises the following steps that S1, two plates are taken, and I-shaped grooves are formed in the plates; s2, the two plates are in butt joint to form a jointed plate, and a gap is formed in the butt joint position of the two plates; s3, arc striking and extinguishing plates are installed at the starting section and the tail end of the gap, and a liner is arranged on the back face of the jointed board gap; s4, a tool jig is used for limiting the jointed board; s5, the jointed plate is welded through deep fusion arc to form a welded plate, and an I-shaped welding seam is formed in a gap; and S6, the run-on and run-off plate and the liner are dismounted from the welding plate. According to the welding method of the high-strength steel plate and the ship, the jointed plates are welded through the deep fusion arc technology, grooves do not need to be fo
