Abstract：To address the issues of low tracking accuracy and excessive manual intervention during the submerged arc pre-welding process of spiral steel pipes，this study designed a real-time weld seam tracking system based on visual sensing and adaptive control technology.This system has effctively improved the accuracy and stability of weld seam tracking in pre-welding equipment，reduced weld deviation rates，minimized welding defects，and enhanced both welding quality and production efficiency.

Key words： pre-welding; laser tracking sensor; weld seam tracking; automatic tracking
