In order to reduce welding stress, decreased welding crack and improve coating performance, a set of complete computer control system was designed and applied to prepare TiCN cermet composite coating by process. The system, which consists of PC, SCM (AT89C52), sensor, interface circuit, pneumatic rammer, corresponding mechanism and valves, can peen the welded seam by a pneumatic rammer which is controlled by the signal from data acquisition card. The system can easily adjust the peening frequency, force, distance, and angle able. The result show that the system can make coatings more inseparable and compacter, less weld defect, and the coatings have an excellent mechanical property.
