Polymer welding
WebThe final weld beads should be fully rolled over, free from pitting and voids, correctly sized, and free from discolouration. When correctly performed, the minimum long-term strength of the butt fusion joint should be 90% of the strength of the parent PE pipe. Butt Welding Parameters. Zone 1: Initial Bead Pressure P1 WebMethods of Polymer Weld Quality Evaluation Miranda Marcus EWI, Columbus OH, USA [email protected] Abstract Evaluation of the quality of polymer welds is essential to the development and production maintenance of a welding process. However, it can be challenging to select an evaluation method due to the wide variety of options.

WebMay 31, 2024 · One example of a common but potentially troublesome change involves moving from an easy-to-weld amorphous material such as ABS, to a much more difficult-to-weld semi-crystalline polymer, such as PP. ABS requires lower ultrasonic stack output (30-70 microns at 20 kHz) for successful welding than does PP (90-120 microns).
