The invention discloses a steel rail welding seam ultrasonic flaw detection coupling agent, which relates to the technical field of steel rail detection, and comprises, by mass, 10-40% of a solvent, 1-3% of a gelling agent, 1-3% of a colloid stabilizer, 0.5-1.5% of an organic sulfur compound, 0.02-2% of an antirust agent, 0.01-0.5% of an auxiliary agent, and the balance of water. According to the ultrasonic flaw detection coupling agent for the steel rail welding seam, the nonionic surfactant is used as an auxiliary agent and has good hydrophilicity and decontamination capacity, so that the coupling agent can be more easily wetted and cleaned by water when encountering rainwater, meanwhile, the adhesive force between the coupling agent and the surface of a workpiece can be reduced, volatilization is facilitated, and corrosion resistance and oxidation resistance are achieved; meanwhile, the performance of the coupling agent is improved, the lubricity of the coupling agent is improved, the surface tension is reduced, the effect of the coupling agent in practical application is improved, and the coupling agent has high reliability.
