Abstract Process principle of reciprocating spray forming large thick-wall tubular was analyzed. The distribution of the mass flux of spray cone and behavior of the deposit track of single layer were studied, a model of deposit of single layer was established on the basis of these research. Aiming at the model and the helix characteristic of the deposit track, the influences of model parameters （Mmax 、a 、d） and mandrel movement parameters （w、v） on the deposit behavior ,and the influences of mandrel radius on deposit thickness of single layer were analyzed. Through the simulating of the deposit thickness overlapped by the deposit profiles of multiple circumrotating cycles,the movement parameters（w、v）of tubular spray forming were optimized.
