The invention provides a production technique for a spray forming composite TBM cutter ring and belongs to the field of mechanical manufacturing and machining. The production technique comprises the steps of spray forming of a composite pipe blank, blanking, forging forming, annealing after forging, rough machining, quenching and tempering heat treatment, accurate grinding and the like. The cutterring formed through the production technique is a composite cutter ring, a low-alloy steel material which is high in anti-impact toughness and low in cost mainly plays a supporting role, and edge parts, used for rock breaking, of the cutter ring are made of a die steel material which is good in abrasion resistance and has certain anti-impact performance; a bimetal interface subjected to high-temperature one-time spray forming serves as a transitional area, metallurgical bonding is sufficient, metallurgical bonding strength is high, and using of alloy elements is reduced to a great extent while the cutter ring cost is lowered; and a series of high-energy-consumption metallurgical processes such as smelting, refining and electroslag remelting are omitted in the whole manufacturing technique, and the production technique is worth applying and popularizing.
