PVDF Product Welding
Problem Phenomenon
Welding joint problems.
Cause Analysis
PVDF can be hot-melt welded for pipe connections; welding temperature and time must be controlled.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Develop welding parameters; ②control welding temperature; ③perform strength and sealing verification; ④train operators.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PVDF welding is key to pipe installation; parameters and operation are equally emphasized.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a reference for troubleshooting similar problems in the future
