1. An automatic welding method for prestressed tubular piles, comprising:
conducting a detection on a connection position between prestressed tubular piles and obtaining a position of a target welding seam, wherein the prestressed tubular piles are arranged along a vertical direction; and
welding the target welding seam around the prestressed tubular piles according to the position of the target welding seam,
wherein the step of welding the target welding seam around the prestressed tubular piles according to the position of the target welding seam is performed by resurfacing welding, and the resurfacing welding comprises:
dividing the target welding seam into a plurality of welding areas according to a width and a depth of the target welding seam, wherein the plurality of welding areas is arranged along the vertical direction;
determining a welding surface of each of the plurality of welding areas, wherein the welding surface of each of the plurality of welding areas is parallel to an outer wall of the prestressed tubular piles; and
conducting welding on the welding surface of each of the plurality of welding areas according to a welding sequence of the plurality of welding areas.
