We study the anomalous W+W−γW+W−γ couplings by performing the production of the W-pair through the process e−p→e−γ∗γ∗p→e−W+W−pe−p→e−γ∗γ∗p→e−W+W−p at the Large Hadron electron Collider (LHeC) and the Future Circular Collider-hadron electron (FCC-he). We examine the pure hadronic, the semi-leptonic and the pure leptonic decay channels of the produced W-pair. We assume the center-of-mass energies of s√=1.30s=1.30 and 1.981.98 TeV and the integrated luminosities of 10-100 fb−1−1 for the LHeC and the center-of-mass energies of s√=3.46s=3.46 and 5.295.29 TeV and the integrated luminosities of 100-2000 fb−1−1 for the FCC-he. The best limits at 95%% confidence level obtained for the anomalous couplings ΔκγΔκγ and λγλγ are Δκγ=[−0.00208;0.00206]Δκγ=[−0.00208;0.00206] and λγ=[−0.00174;0.00834]λγ=[−0.00174;0.00834]. By comparing these limits with the experimental limits, we present the potentials of the process and future epep colliders.
