Dear Chandra,
You didn't give any details about the WPS and PQR availability for the HDPE Butt Fusion welding and following checks shall be done to ensure the quality,
1) 180 Deg Bend Test (4 pieces) for the 1st fusion joint per shift/day or any change in welding parameters like fusion temperature, time & pressure.
2) Check the Mismatch prior to start heating and fusion.
3) External Weld bead should be uniform for the both side.
4) Weld bead to be shaved to check the miss alignment or lack of fusion.
Regards,
Mohan, Q8.
