The effect of friction welding condition on the friction welding phenomena of high density polyethylene was investigated with a brake type friction welding machine which was built as a trial for polyethylene.
The experimental results are as follows;
1) The initial torque, steady torque and total loss were increased by increase of friction pressure. These tendencies were the same manner as carbon steel.
2) The rate of total length of rotated side and fixed side changed with friction welding condition. These phenomena were different from the those of carbon steel.
3) The friction welding condition range of polyethylene for good appearance became narrower than that of carbon steel.
4) In the case of polyethylene, the environment in workshop became worse by occurrence of cotton dust, scatter of liquefied polyethylene and bad smell, when friction welding was investigated except pertinent friction welding condition. Therefore, this material required sufficient care, when friction welding condition was selected.
