The invention provides a welding method for an oversized end socket. The welding method comprises the steps that the oversized end socket is decomposed into a plurality of flaps with the same size in the longitudinal direction; according to the design requirements of the petals, machining of the petals is completed, and then the machined petals are welded to a welding tool; the welding tool is spliced and assembled, the spliced longitudinal welding seams are welded, and the remaining two symmetrical longitudinal welding seams are not welded and serve as matching openings; the two halved structures enter a flaw detection chamber for flaw detection; after the flaw detection inspection is qualified, matching welding is carried out on the matching opening; and performing flaw detection on the matched opening after matched welding, and obtaining the oversized end socket after the flaw detection is qualified. According to the method, the perimeter size precision of the oversized seal head can be guaranteed through
