Zusammenfassung:	The invention relates to a machining process for a strain-hardening seal head. The machining process comprises the following steps: making welding process assessment; selecting and using a steel plate; cutting a wafer; molding the seal head; chamfering; pickling; polishing. According to the machining process, a high-quality steel plate material is selected and used, and the strength of the steel plate is controlled so as to ensure the performance and the molding quality of a welding joint of the seal head; the performance of the welding joint is ensured by pre-stretching (through 9 percent deformation) a welding test plate before the seal head is made; the requirement on the appearance size of the seal head is met by adopting an accurate mold.
