Seamless welding method of ultrahigh molecular weight polyethylene plates

The invention relates to a seamless welding method of ultrahigh molecular weight polyethylene plates; the method realizes seamless welding through filling ultrahigh molecular polyethylene powder in a groove, is excellent in welding effect, and can totally fuse two plates to achieve a purpose of seamless welding; the rising temperature and the adding pressure in the welding process are substantially consistent with the rising temperature and the adding pressure in the process of pressing the ultrahigh molecular polyethylene plates; the ultrahigh molecular polyethylene plate powder added in the groove is the same with materials in the pressing of the plates; and the appearances and the physical performances of the plates at the butt joint parts are both consistent with that of the ultrahigh molecular polyethylene plates required to be in butt joint.
