Techniques for welding thermoplastic tubes |
摘要 |
Two thermoplastic tubes are welded together by pre-cutting the tubes to create two ends which are axially aligned when placed in a holding device. A wafer is inserted in the space between the cut ends and the wafer is heated to melt the cut ends while the cut ends are in a non-flattened condition. After the wafer is removed the melted cut ends are pressed against each other to weld the cut ends together.
