The invention discloses a heavy weight drill pipe manufacturing technology comprising the steps: 1) bar stock inspection; 2) thickening both ends of bar stocks; 3) thickening the middle of the bar stocks; 4) drilling and boring deep holes; 5) heat treatment; 6) turning and machining the outside surface; and 7) thread machining. According to the above heavy weight drill pipe manufacturing technology, small bar stocks are adopted, and both ends and the middle of the bar stocks are thickened, so that the shape of heavy weight drill pipe blanks is closer to the appearance of the finished products of the heavy weight drill pipe, and the subsequent machining is performed; the materials are saved, and the turning and machining time is reduced; and the cost is reduced, and the production efficiency is improved.
