去年我们有批塑料管需要焊接,采用电烙铁焊接的质量达不到要求,后来我们试验采用摩擦焊接法,经过一段时间摸索获得成功。摩擦焊接设备我们采用C620型车床,管子一端夹在卡盘上,另一端夹在尾座上,转速为480转/分,焊接面压力不可太大,开车10～15秒钟,当两接触面呈胶状时,停车,这 Last year we had a batch of plastic pipes that needed welding. The quality of soldering iron welding did not meet the requirements. Later, we used friction welding to test and succeeded after a period of exploration. Friction Welding Equipment We use C620 type lathe, one end of the tube is clamped on the chuck, the other end is clamped on the tailstock, the speed is 480 r.p.m., the pressure on the welding surface can not be too big and the driving time is 10 to 15 seconds.
