This paper describes the irradiation effects on the tensile characteristics of welded polyethylene. Low density polyethylene plates, 2mm in thickness, were used in this experiment. These polyethylene plates were welded by means of a semiautomatic heating plate welding apparatus and exposed to various irradiation doses of neutron. Examination of X-ray diffraction pattern and measurement of X-ray diffraction intensity were made during tensile test of the welded part of neutron irradiated polyethylene. It was found that the irradiation effects on the welded part are similar to those on the base material of polyethylene and molecular orientation tendency during tensile test is restrained with increase of irradiation does.
