The invention belongs to the technical field of flux-cored wires, and relates to a high-titanium composite wear-resisting plate flux-cored wire free of cracks after welding. In the preparation of the flux-cored wire, a low-carbon steel strip HS1 is adopted outside, the thickness is 0.3-0.3 mm, and the width is 16 mm. Various alloy powder is wrapped in the alloy powder, and the alloy powder is added and processed according to the filling ratio of 45-53%. The welding wire provided by the invention solves the problem that a common high-chromium cast iron type composite wear-resisting plate has cracks after being welded, the shock resistance of the composite wear-resisting plate is improved, and the application range of the composite wear-resisting plate is greatly enlarged. The post-welding hardness of the product is slightly higher than that of Cr7C3 and is HRC62-66, and the wear resistance of the product is 2.2-3.0 times that of a cracked high-chromium cast iron composite wear-resisting plate. And the impact r
