The interaction between nonlinear solitary magnetic-flux waves (fluxons) in a long Josephson junction is considered with account taken of dissipative processes and of the bias current. The system is described by the perturbed sine-Gordon equation. Perturbation theory calculations show that weak dissipation and a weak bias current can significantly affect the dynamics of a fluxon system and lead to the formation of soliton complexes moving as a unit with practically constant distances between the solitons (congealing of fluxons). The asymptotic results obtained by the perturbation-theory calculations are confirmed by numerical experiments.
