FIELD: process engineering.
SUBSTANCE: invention relates to equipment for welding plastic materials, particularly, to jointing polymer tubes together by heated tool, and may be used in mounting hot and cold water supply systems mounting. Proposed tool has, at least, one hole in tube tool outer wall arranged so that surface formed by walls of this hole crosses that of outer cylindrical wall of tube tool seat annular groove along the line having, at least, one point of intersection with cylindrical wall surface of seat annular groove with surface of seat annular groove bottom.
EFFECT: higher quality and reliability of joint.
