How plastic welds retain a molecular 'memory' of their former surfaces to strengthen pipe joints
Welding plastic is a critically important part of everyday engineering—especially for preventing leaks in underground water and gas pipes. For decades, engineers have understood that a properly welded joint in polyethylene pipe can be just as strong as the pipe itself, if not stronger. However, the reason for this strength has remained a mystery.
