PROBLEM TO BE SOLVED: To provide a method capable of analyzing a Ti-based precipitate in a welding part of a steel member. SOLUTION: The method for analyzing a Ti-based precipitate in a welding part of a steel member includes the steps of sampling collecting a sample from at least one site in a welded metal part and a welding heat affected part in a steel member containing a Ti-precipitate welded or subjected to heat-treatment equivalent to welding, dissolving the sample collected using a Br-methanol solution, filtering the Br-methanol solution obtained after dissolving the sample, soaking a collecting filter after the filtration in a solution with dispersibility to recover the Ti-based precipitate separated on the collecting filter in the solution with dispersibility, and filtering the solution with dispersibility containing the Ti-based precipitate separated one or more steps with the separation filter to analyze the Ti-based precipitate recovered on a separation filter or in a filtrate.
